Alloy structural steel for forging


The carbon content of alloy structural steel is lower than that of carbon structural steel, generally in the range of 0.15%-0.50%. In addition to carbon, it also contains one or several alloying elements, such as silicon, manganese, vanadium, titanium, boron and nickel, chromium, molybdenum, etc. Alloy structural steel is easy to harden and not easy to deform or crack, making it easy to heat treat to improve the properties of the steel.


Alloy structural steel is widely used in the manufacture of various transmission parts and fasteners for automobiles, tractors, ships, steam turbines, and heavy machine tools. Low-carbon alloy steel generally undergoes carburizing treatment, while medium-carbon alloy steel generally undergoes quenching and tempering treatment.
