Alloy steel material is made by combining carbon steel with one or several alloying elements. Alloying elements include manganese, silicon, nickel, titanium, copper, chromium and aluminum. Adding these metals can produce specific properties that conventional carbon steel does not have. These elements are added in different proportions/combinations to make the material have different effects, such as increasing hardness, increasing corrosion resistance, increasing strength, and improving formability. In addition, the weldability will also change.
* Enhanced hardenability.
* Enhanced corrosion resistance.
* Maintain hardness and strength.
* Almost all alloy steels need heat treatment in order to exert their best performance.
Chromium: increases the hardness, toughness and wear resistance of the alloy steel material.
Cobalt: used in the manufacture of cutting tools; improved hot hardness.
Manganese: improves the surface hardness, and improves the resistance to strain, hammer and impact.
Molybdenum: enhances the strength, improves the impact resistance and heat resistance.
Nickel: improves strength, toughness, and corrosion resistance.
Tungsten: increases the hardness and improves grain structure, providing improved heat resistance.
Vanadium: improves the strength, toughness and impact resistance, and improves corrosion resistance.
Chrome vanadium: greatly improving the tensile strength, it is strong, but easy to bend and cut.
