Alloy steels contain large amounts of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other generally accepted elements such as manganese, sulfur, silicon and phosphorus. This alloying element is usually added to increase hardness, strength or chemical resistance. Pipes made of alloy steel have excellent properties. These are typically developed for energy-related applications involving oil and gas drilling and are subject to stresses in machine components. Alloy steel pipes are also used in everyday life, catering to domestic, professional or industrial needs. In recent years, with the economic growth, the demand for alloy steel pipes has been increasing.
We specialize in supplying precision engineering alloy steels for various engineering applications, available in various grades of ASTM A335 alloy steel pipes, grades P1, P2, P5, P9, P11, P12, P22, P23, P91, P92 and ASTM A213 alloys Steel pipes, grades T2, T5, T5b, T5c, T9, T11, T12, T22, T23, T91, T92. These grades are available as alloy steel pipes.
