YOUR RELIABLE PARTNER FOR QUALITY ALLOY STEEL
Alloy steel referring to low alloy steel is contained with a variety of elements which are added strictly in addition to the carbon.Typical alloyed elements are Molybdenum, Manganese, Nickel, Silicon, Aluminium, Chromium, and Vanadium.They are used to improve its mechanical or physical properties,such as wear resistance,strength, hardenability,corrosion resistance,ductility, formability, weldability and so on.Alloy steel is widely used in oil and gas,aerospace,automotive, wind power and defense industries etc.
