Alloy steel contains substantial quantities of elements other than carbon such as nickle, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as menhanese, sulfur, silicon,and phosphorous. Addition of such alloying elements is usually for the purpose to increase hardness, strength or chemical resistance.
