Alloy steel pipe is made of high quality carbon steel, alloy structure steel and stainless heat-resistant steel, which is hot rolled (hot extrusion, hot expansion) or cold rolled (drawing). Alloy steel pipe is mainly used in power plant, nuclear power, high pressure boiler, high temperature superheater and reheater and other high pressure and high temperature pipeline and equipment. Alloy steel in addition to iron, carbon, but also added one or more alloy elements to form iron carbon alloy. According to the different added elements, and adopt appropriate processing technology, can obtain high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties. The main alloying elements of alloy steel pipe are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth and so on. Generally smelted in the electric furnace alloy steel pipe according to the use is divided into 8 categories: alloy structure steel pipe, spring steel pipe, bearing steel pipe, alloy tool steel pipe, high-speed tool steel pipe, stainless steel pipe, heat resistant steel pipe, low temperature steel pipe. Low alloy structural steel has high strength, enough plasticity and toughness, good welding performance. Widely used in buildings, Bridges, etc. Commonly used low alloy structural steel grades are 16Mn, 15MnTi and so on. Alloy carburizing steel is mainly used for hard surface and wear resistance, good impact resistance of the core toughness parts, such as gear, CAM, etc., with good carburizing ability and hardenability. The commonly used alloy carburized carbon steel pipe materials are 20Cr, 20CrMnTi. Alloy modulated steel pipe after quenching and tempering treatment has high strength and good plasticity and toughness, with good comprehensive mechanical properties. Commonly used alloy modulated steel pipe has steel grades 40Cr, 40CrMn and so on. Alloy spring steel tube is mainly used to manufacture various elastic elements. Alloy spring steel pipe has high elastic limit, high flexural ratio, high fatigue strength and enough toughness. The commonly used alloy spring steel pipe material is 60Si2Mn. Rolling bearing steel pipe has high hardness and strength, high elastic limit and contact fatigue strength, enough toughness and hardenability, high wear resistance, and enough corrosion resistance. Commonly used rolling bearing steel pipe has steel grades GCr15, GCr15SiMn.
