15CrMoR belongs to the boiler and pressure vessel steel plate. 15CrMoR itself not only has a very high strength and also has a certain toughness wear resistance, fatigue resistance, impact resistance, corrosion resistance, resistance to low-temperature impact and welding and easy processing performance, often used in pressure vessels and boiler manufacturing, for example; pressure vessel manufacturing, petrochemical machinery manufacturing, petroleum equipment manufacturing, environmental protection equipment manufacturing, liquefied gas tanks, manufacturing, gas cylinders, nuclear power manufacturing ship pressure vessel license, head manufacturing and other applications are quite wide. Manufacturing, gas cylinders, nuclear power manufacturing ship pressure vessel license, head manufacturing and other applications are quite extensive.
The mechanical properties of 15CrMoR are excellent. At room temperature, its tensile strength is usually in the range of 500 to 650MPa, yield strength of 300 to 400MPa, elongation of 18% to 22%. At high temperatures, its tensile and yield strengths decrease, but the creep strength increases significantly. At 400°C, its creep strength is about two times higher than at room temperature. In addition, it has a wide range of hardness between 180 and 250 HB.
15CrMoR default normalized delivery, but also with it is also to do normalized + tempered, sizing, 1 carbon 2 carbon 3 carbon, different delivery states will present different performance indicators and uses, so in the choice of delivery state should be based on the use of the moment to do a good job of harmonizing standards.
