Alloy Steels And Alloying

Alloy Steels And Alloying: Know The Purpose

See how alloying contributed to the alloy steels’ possessed mechanical and physical properties.

alloy-steels-and-alloyingAlloy steels are one of the alloys with super high strength, commonly used in a wide variety of industries. Other than carbon, alloy steels are also formed out of many alloying elements which include nickel, sulfur, chromium, molybdenum, silicon, vanadium, manganese, and cobalt.

The different mechanical properties the material exhibits and the physical attributes it displays depending on the elements present in it – which is combined together due to alloying. For example, the surface hardness of the material is determined by the carbon content while the depth of hardness depends on the alloy it contains.

Pure metals, compared to alloy steels, are generally softer and lack some of the important metallic and physical properties like boiling point, melting point, gravity, density, ductility, malleability, heat and electrical conductivity to mention a few. That is where alloying comes into play. Alloying truly plays big in enhancing a material’s both physical and mechanical properties, that is why many metal suppliers are starting to find innovative ways to come up with high class of steels and metals to make them fit in super demanding applications.The purpose of alloying relatively falls on the following goals:

The purpose of alloying relatively falls on the following goals:

  • Strengthen the ferrite and improve corrosion resistance
  • Come up with better hardenability and improved toughness, machinability, and ductility
  • Improve grain size control and enhance strength
  • Enhance wear resistance
  • Come up with an improved cutting ability, case hardening properties, as well as high/ low temperature stability

Alloying has positively contributed to the production of alloy steel. At present, alloy steels have been sought and used by a lot of industrial manufacturers for a lot of high-performance applications since they are proven to exhibit desirable properties such as the following:

  • High strength
  • Great hardenability
  • Higher temperature strength
  • Great ductility at high strength
  • Less cracking and distortion
  • Excellent machinability at high hardness
  • Better stress relief at given hardness
  • High endurance and elastic ration strength

However, as alloy steel continues to grow when it comes to demands, alloy steels also become one of the priciest steels in the market. These alloys also get some slight tendencies toward austenite retention and temper brittleness in grades.

Cast iron or Cast steel - Which is better

Cast Iron or Cast Steel: Which is Better?

Cast iron or Cast steel: Which is better? Enough talk. We compared which of the two exhibits the best strength and properties. All pros and cons laid out!

Cast iron or Cast steel- Which is betterCast iron and cast steel have each of their own important role in industrial applications, but there is an existing argument to which is better – is it cast iron or cast steel?

The casting method applied to all types of materials is highly essential in the production since it can offer an exceptional design which eliminates the need for fabrication and additional assemblies. There are actually a lot of materials applicable for casting including those of metal and synthetic types. The most popular among all are iron and steel which both exhibit exceptional mechanical properties good for ranging applications.

Both feature excellent characteristics, but it also important to know material’s advantages and disadvantages though, as summed up in the table below:

Material Advantage Disadvantage
Cast Iron
  • Good casting properties
  • Good wear resistance
  • Good machinability
  • Good vibration damping
  • Low notch sensitivity
  • Low tensile strength and elongation
  • High cost for production
  • Complex production process
Cast Steel
  • Design flexibility
  • Allows hollow cross-section parts and complex shape formation
  • Strong variability
  • Superior mechanical properties
  • Has bad shake-suction
  • Low wear resistance
  • Low casting performance and mobility
  • Has higher cost compared to cast iron

As we reveal the difference between the two materials (both their pros and cons), we can already think where they should be perfectly suited depending on the kind of environment or pressure – as long as both materials can both do the best job. What matters most upon the performance of these materials is their composition and phase structure which can affect their mechanical properties. There are elements like graphite flakes present in iron composition and these flakes cause iron’s brittleness, for example.

Yet, there has already been a method of adding many types of alloy steel and iron in order to achieve those desired mechanical and physical properties. To mention a few, elements like chromium which adds more corrosion resistance and manganese which increases toughness are added to the material. All alloying elements have each of their own contribution to the material’s overall better performance.

These materials both have their advantages and disadvantages, but they are still eminently used in a wide variety of applications.

duplex stainless steel

Duplex Stainless Steel: Passing Rigid Steel Standards

Duplex stainless steel gains great popularity with its excellent features and low cost – making more possible advancements in steel crafting.

Duplex stainless steel has originated in 1920s due to the existent pursuit of making advances in steelmaking techniques with respect to the nitrogen control.

duplex stainless steelThough stainless steel is classified into two different types such as the austenite and ferrite, metalworkers still see important technical weaknesses in both types.

Particularly, both of these types are easy to make and fabricate but they still do lacking features that led to more advancements in engineering high class of steels.


  • Has low strength and low resistance to stress corrosion cracking


  • Has poor weldability in thick sections, low strength, and poor low temperature toughness

Due to lack features in both, duplex stainless steel comes in the way. Duplex stainless steels are becoming popular in the manufacturing field and have been distributed and offered by major steel mills for their excellent features:

  • Greater corrosion resistance
  • Resistance to stress corrosion cracking
  • High Strength
  • Good price stability
  • Low cost

Duplex stainless steels consist of two mixed microstructures grains which are the austenite and ferrite. The combined forces of two makes duplex have strength that are roughly twice as strong as compared to regular austenitic and ferritic steels. They also have improved resistance against localized corrosion, crevice cracking, pitting, and stress corrosion cracking which makes it ideal for a wide range of high temperature applications.

Duplex stainless steels have a high amount of chromium and molybdenum but have lower amount of nickel contents. Thus, compared to ordinary stainless steel, duplex stainless steels are lighter in weight and lower in cost – such feature that is most sought by metalworkers in their manufacturing pursuits.

The excellent mechanical and physical properties of duplex stainless steels are achieved with lower alloying elements found in its content, allowing their use to be used cost-effective for a variety of applications.

All of those sum up why duplex stainless steel earns the increasingly growing demand in the market. Most of the manufacturers have preferred it for almost all types of applications including construction and manufacturing. Aside from the high strength, manufacturers see the great convenience in the big cost savings they got from using such materials.

grinding steels

Grinding Steels

Applying the grinding technique to steels requires guidelines and proper implementation of tools and inserts to achieve quality results.

Steel has been thoroughly used by a lot of manufacturers and metalworkers nowadays.

grinding steelsThe almost perfect feature of steel makes it pass all rigid requirements when it comes to mechanical properties and excellent grade.

Steel is fused with different elements that have excellent characteristics on their own – alloyed together to form one solid metal that can withstand high performance applications.

Steels are the best materials for withstanding high temperature environments that require high tensile and yield strength and excellent resistance to corrosion and oxidation.

Steels are iron-based metals. By its improved strength, steels are common raw materials used for manufacturing parts for automotive engines, aircraft structure and turbines, and even for chemical plants and medical tools.

Machining Steels

Steel materials are challenging to be machined compared to other metals due to its kind of hardness feature. The higher the steel’s alloying content, the harder it is to machine. Mostly, this challenge falls to austenitic steel which contains a maximum percentage of chromium and nickel elements. But special metallurgical treatment has been made to enhance the machinability of steels.

In addition, hard steels need the rigid use of heavy machineries when machining. There is a need to obtain knowledge of the factors contributing to the machinability of steels to achieve complex precision engineered parts in high volumes. Mechanical properties, grades, alloyed elements, and strength are just four of the contributing factors that influence the machinability of steels.

Grinding Steels

Obtaining finer surface finish in grinding steels involves continuous abrasive metal removal. Thus, an implementation of healthy guideline to grinding steel is necessary especially when grinding hard, course part. For such operation, there are key variables to be followed such as: three-point positioning, consistent grain dressing, proper automation, and coolant application. Keeping a close watch to those key variables makes the operation running in a smooth flow, enabling to achieve that consistent part results in a single pass!

Since the operation is too continuous and rapid, tool grains on the grinding wheels might get worn out so redressing them is highly encouraged. To gain that precise surface finish and tight diameter tolerance, grinding procedure should be put properly into place.

centerless Grinding

Innovations for Centerless Grinding Issues

Centerless grinding is best in achieving consistent part results at fast lead times but issues are inevitable – this calls for innovations to improve operation and productivity.

When it comes to mass production, centerless grinding receives all the recognition in achieving consistent part results at fast lead times.

centerless GrindingThe multifunctionality it performs allows the option to not just grind and cut the bar alone, but also polish and clean it to its accurate surface finish.

This cylindrical operation is highly applied in the mass variety of either round or complex components where quality parameters like tight tolerance, cylindricity, and roundness are crucial.

As of today, the cost of manufacturing is highly increasing which has pushed manufacturers to extract more production out of grinding machines to at least, lower the cost per piece. Let’s say a supplier of components for high performance application such as automotive engines, aircraft parts, turbines, and endurance racing will need to have boost-production but at reduced lead times. Outsourcing this required application is considered the best aid that put centerless grinding in place and specialization. Yet, it entails a large machine investment and skill not really common in the machinist workforce.

Thus, we can’t deny the fact that centerless grinding can be quite expensive and dirty; but there are best suggestions from experts to improve productivity and quality level while reducing the cost of centerless grinding process:

Floor Space Utilization

  • The land cost is always high which has hit the biggest percentage in the capital including the facilities and the equipment. This initiates the need to reduce floor space dedication to a single machine only and machine footprint. Upon this rising issue, some operators come up in designing small models of grinding machine. In addition, they add rigidity by adding weight to make it equal to the traditional models. This helps save more space for other operations.

Productive Dressing Time

  • Dressing is the major non-productive phase in the process. Thus, there really is the need to devise operations in order for the dressing time to be utilized productively. There is where the use of diamond abrasives comes in place. Diamond abrasives don’t get dull right away which are much effective in grinding parts. This leads to more production of parts with consistent finish even with less redressing.

Reduced Working Costs

  • This best explains why an automation implemented in the operation is important and effective. Running an automation helps the operator to do more than one task and run more than one machine. Skill is highly considered in this phase. Thus, it is important to hire a skilled person who knows how to look after the setting and do a regular inspection of the final pieces for the grinding machine. The implementation of CNC option also aids in the reduction of operator’s intervention to a large extent to reduce costs.

Energy Efficient Motors

  • The increasing cost of power is happening right now, thus more energy efficient motors must be explored.

Efficient Formulation

  • The production of fuel-efficient vehicles is important to run the operation, however, this is also greatly affected by the increasing rate of fuel prices – which is a burden to the manufacturers. This opens up the need to explore and try different materials and techniques to reduce vehicle weight. And if possible, machines with the capability to grind such components need to be devised. An installation of Variable Frequency Drive to the grinding wheels helps in achieving constant surface speed. This also aids in the reduction of the dressing frequency as the wheel diameter is reduced, resulting in an optimum use of the grinding wheels.

Accessories and Equipment in Centerless Grinding

Sophistication must not only come in a machine but also productivity and multifunctionality – for an optimum centerless grinding operation.

The success in any machining operation doesn’t lie only on skills or facilities, though they are one of the most critical segments in the process, it is also important to take the machine accessories and tools into great consideration.

Accessories and The Machine

Accessories and Equipment in Centerless Grinding - Ohare Blog 03Sophistication must not only come in a machine but also productivity and multifunctionality. But how are all these achieved?

Of course, skill, preventative maintenance, equipment, and tools are always part of the process but the proper implementation of machine equipment may also have its part.

To make the operation successful and much more effective in centerless grinding, there should be an involvement of machine tools and accessories (such as outboard supports, ejectors, supporting rollers) in place. The use of these accessories and operator assisted devices makes the work more efficient, improve grinding application, and achieve the better tolerance required in every bar.

In all kinds of centerless grinding operation, may it be thrufeed or in-feed, the presence of such tools is taken into high importance by operators for optimum part removal with controlled bar straightness.

Proper setting and attachment

Thrufeed grinding

For thrufeed grinding, the work size compensation is one significant factor to consider in attaining tight tolerances. Simple supporting is not enough to have an effective centerless grinding operation. There can workpieces that weigh 200 kg or even more, so support tables (with self-contained drives) are needed to help rollers enhance turning rate or the high rotational speed of the regulating wheel.


• Imparts peripheral speed which is equal to that of regulating wheel’s rate
• Enhances speed proximity

Push button/ Gage Directed Actuation

• Basically for work size control
• Also, works for compensating wheel wear
• Withdraws the wheel slide when balancing thermal effects on the work size is necessary

In-feed grinding

If you are looking for less practice times but with exacting diameter tolerance in every infeed grinding operation, machine accessories and attachments should not be ignored. These tools make the set-up and operation more efficient and make it even more possible to gain fast machining production.

Grinding small part diameters and even out-of-round parts is highly complex requires attachments to hold the workpiece in proper place.

Harmonic Drives

• They ensure good repeatability for the fine compensation and grinding cycle
• Allow incremental movement of slides

Precision Ground Ball Screw

• This makes it possible for achieving great tolerance and roundness up to even .0002” in 56” length

Twin-Grip Mounting

The combination of those necessary attachments enable both wheels (regulating wheel and grinding wheel) to use the “Twin-Grip” mounting, which is essentially used in eliminating and resisting wheel-separating wheel pressures even under heavy loads. Aside from proper placement and controlled gap, this mounting is critical and important in providing maximum rigidity between spindles that affects the consistency of part geometry.

stainless steel bars

Tips On How To Choose The Right Grade Type Stainless Steel Bars

Weighing of important qualities is considered in the selecting perfect material to use in producing products like stainless steel bars, medical bars, etc.

As we all know, stainless steels are manufacturing materials that have good strength, corrosion-resistance, and fabrication resistance.

stainless steel barsThese materials can always meet a vast range of design standards and this includes service life, load, and low maintenance. Thus, choosing or selecting the right stainless steel types and grades needs thorough weighing of four qualities in important order:

A. Heat or Corrosion Resistance

– This is the basic reason to consider for specifying stainless steel products. There is a need to have knowledge about the nature of stainless steel environment and the level of required resistance to heat or corrosion of every stainless steel material.

B. Mechanical Properties

– The basis for steel selection is the combination of strength and corrosion resistance. This quality involves particularly elevated or low temperature and strength at room.

C. Manufacturing Operations

– This focuses on the operations on how the product will be made like these following examples: machining, grinding, welding, chamfering, forging, stamping, roll forming, four-slide operations. The quality of a certain steel product really depends on the specific processes that the steel materials undergo to reach hardness, accuracy, and perfect roundness. Among the most sought mechanical operations now is the centerless grinding that is proven to produce accurate roundness.

D. Whole Cost

– Considering the expenses of production and material as well as the increasing savings of product with durability but maintenance-free.

Well, the selection of the particular steel particularly depends on what is required on a particular application. If there is an urge to create stainless steel bars, then more likely austenitic steel types should be used. On the other hand, medical steel bars are much available in martensitic types of steels. The environment of a certain stainless steel product including the chemical processes in which the steel is formed and what will also determine its features like resistance to corrosion and heat will help determine what type of stainless steel material to use. Aside from those important qualities that have to be considered, there are also other factors that need to be taken into account.

1. Required Strength – Austenitic, martensitic, duplex, and PH steels can obtain higher strengths. Strengths may differ according to the series of processes the materials that undergo. For example, forming and welding processes oftentimes influence what material and grade should be the most suitable.

2. Operation’s Temperature – Corrosion rates are usually accelerated by high temperatures. Thus, it signifies a higher grade. Well, mostly low temperatures require hard austenitic steel.

3. Required Product Form – Not all grades can be obtainable in all product sizes and forms like sheet, tube, and bar. Moreover, austenitic steels can offer wide range of dimensions that all product forms can be formed out from it. So mostly stainless steel bars are created from austenitic type of stainless steel.

Well, steel products forms and sizes may differ according to the type of steel used. Austenitic for example, as what has been mentioned, can be perfect for creating stainless steel bars. The certain types of steels undergo various cooling and hardening processes which result to different characteristics in each material.

Almost all stainless steel have good weldability. Therefore, it needs to be taken into account that joint forces and any filler metal should be kept from contamination like oxide and organic material.

In selecting welding filler materials for stainless steel, a principal concern in matching the major properties of the base metal is considered. Moreover, for duplex and nominally austenitic stainless steel, there should be some control over the ferrite content of the weld metal.

To sum it up, it is not just the type or grade of stainless steel that has to be taken into account, but as well as the environment, the operations, and all – for these will greatly affect the quality of the product. Quality is always sought in very product and purchase.

Discover How Centerless Grinding Operates - Ohare Blog 04

Discover How Centerless Grinding Operates

To operate a centerless grinding process takes skill and further understanding of its rules to be able to attain flawless results out from the raw materials.

Discover How Centerless Grinding Operates - Ohare Blog 04Centerless grinding is a kind of metalworking operation that highly requires full understanding of its basic fundamentals to achieve quality and consistent results. This kind of grinding process is very crucial resulting to most operations to fail in achieving the desired quality due to the lack of understanding of its basic principles.

Basically, centerless grinding is a kind of OD grinding process which is far different from other cylindrical processes in which the workpiece is not mechanically forced with pressure. The workpiece must be placed above the centerline of the wheels to let the grinding process create a rounding action on the workpiece.

Other traditional OD machining processes like center-type or chucker-type grinding require center holes, drivers, or workhead fixtures – centerless processes don’t. Instead, a workblade that is located between the grinding wheel and regulating wheel supports the workpiece on its outer diameter. The grinding wheel has much higher velocity than the regulating wheel. The presence of these three components like the workblade, the grinding wheel, and the regulating wheel makes the grinding process attain a perfect centerless grinding operation.

Major Parts that do the Grinding Process

  • Grinding Wheel

    The grinding wheel is the part of the machine that does the grinding process and has higher speed than the other wheel. It applies a downward force to the workpiece and is placed on affixed axis.

  • Regulating Wheel

    This wheel is the movable wheel and has slower speed than the grinding wheel which applies a lateral pressure to the workpiece.

  • Workblade blade used for abrasive cutting.

Why Centerless?

The idea of “centerless” may confuse manufacturers. But from the word itself, “centerless”, the centerless grinder has no centers, appearing to have no control on the workpiece. That’s what makes the operation indeed crucial and difficult. If proper fundamentals are acquired in the process and if it’s set up properly, centerless grinding will achieve surface finish, roundness, and dimensional tolerances in the metalworking operation. What makes this grinding operation stand out for other processes is that it comes up with a flawless roundness of workpiece blanks – if the process is done through properly sticking to its fundamentals and with a proper handling of the grinding wheel, the regulating wheel, and the workblade.

There are numerous companies that offer a lot of services when it comes to manufacturing parts for different production of automobiles, aircrafts, hardware, and constriction of raw materials. Among these companies, only one is considered to be the company which worth your trust.

The great actions to prepare firsthand in the grinding process and all other machining operations are highly one of our tasks here in O’Hare Precision Metals, LLC.
