Alloy Steel contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous. Addition of such alloying elements is usually for the purpose to increase hardness, strength or chemical resistance.
Pipes made of alloy steel have exceptional performance properties. These are generally developed for energy-related applications involving oil and gas drilling and are subjected to stresses in machine parts. Alloy Steel Tubes are also used in daily life, catering to the domestic, professional or industrial needs. In recent years, the demand for alloy steel tubing has been increasing along with the economic growth.
