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.
