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 depend 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:

  • 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 upon 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.

At O’Hare Precision Metals, LLC, we always include a big inventory of alloys and metals for different types of manufacturers, ranging from large to small entities. We tailor our products, providing you with much better surface condition, increased yield, high tensile strength, and the tightest diametrical tolerance.

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 analogy 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 alloys to 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.

Amazing Structural Steels Now Stand Towering In Urbanization

As structural engineers sought for more advancements and development in construction, they opt for the application of structural steels for their excellent mechanical properties and metallurgical compositions.

cologneStructural steelworks now come spreading in the entire face of urbanization. As structural engineers sought for more advancements and development in construction, they opt for the application of structural steels and other materials upon each construction project.

Steel has been recognized as the best material that possess the mechanical properties required in construction and engineering application. Few of the known properties steels exhibit are ductility, durability, corrosion and oxidation resistance, and recyclability. There are still a lot of things that steels do possess that let it earn the highest demand in the industry.

Steel not just stands as a foundation in the overall framework of a building, but now they do also dominate in the appearance of each infrastructure that appears glinting in the sun.

The reason behind this great innovation is that structural steels exhibits excellent mechanical properties and characteristics. These steels do the job far better than wood and other materials.

Fire Resistance

For fire protection is one of key objectives in constructing infrastructures and building. Protection and resistance of the building against fire makes its life last long over many years. Thus, steel and other sort of metal is preferred by structural engineers and designers to meet that certain requirement. Steels not just exhibit the resistance against corrosion and oxidation but as well as fire resistance.

Strength

Steel possesses high levels of strength and hardness that enable it to withstand across an extensive range of extreme temperatures and severe environment and condition. The components that contribute much to the tough strength possessed by these steels are the different compounds and alloying elements found intact within its composition.

Mold

Steels can fight off mold formation on its surface. Structural steel has been used to minimize infestations of mildew and mold in residential building.

Constructability

Steel has the important mechanical properties such as weldability, machinability, and fabricability, so it can developed nearly to any shape – either welded or bolted together in construction.

Tallest structures nowadays are already constructed with structural steels because of its high strength-to-weight ratio and constructability. It has also been observed that companies rely on the application of structural steels as it entails a return of profit for any construction project.
