What material is 12Cr1MoV
1, 12Cr1MoV is a chromium molybdenum vanadium alloy structural steel, its composition contains 12% chromium, 1% molybdenum and 0.25% vanadium. Other elements include carbon, silicon, manganese, phosphorus, sulfur and small amounts of copper, nickel and titanium. This steel has high strength, corrosion resistance at high temperatures and good malleability, and is often used in the manufacture of boilers, pipelines and petrochemical equipment at high temperatures and pressures.
2, in terms of chemical composition, the carbon content of 12Cr1MoV is 0.08-0.15%, the silicon content is 0.17-0.37%, the manganese content is 0.40-0.70%, the phosphorus content is less than 0.025%, the sulfur content is less than 0.025%, the chromium content is 0.90-1.20%, and the molybdenum content is 0.25-0.35%. The content of vanadium is 0.15-0.30%, the content of copper is less than 0.30%, the content of nickel is less than 0.30%, and the content of titanium is less than 0.02%. The content of these elements has an important impact on the performance and use of 12Cr1MoV. Wugang Xinze steel Yang Meng
3, 12Cr1MoV steel plate mechanical performance is very good. After normalizing and tempering treatment, its yield strength can reach more than 380MPa, tensile strength can reach more than 540MPa, and the elongation is about 17%. This means that 12Cr1MoV steel has excellent strength and ductility, making it suitable for use in high-stress working environments and in situations where shock and vibration need to be resisted. In addition, it also has excellent corrosion resistance and wear resistance, and has good stability against hot and cold deformation, thermal expansion and high temperature oxidation. # 1522 # 501 # 5285
4, compared with other materials, 12Cr1MoV steel plate has a longer service life and can withstand higher pressure and temperature. Therefore, it is widely used in national defense, nuclear power, petrochemical, electric power, boiler manufacturing and other fields. In nuclear power plants, 12Cr1MoV steel plates are used to manufacture pressurized water reactor pressure vessels, which have very good radiation resistance and can operate stably in a high radiation environment for a long time. In addition, in the boiler manufacturing industry, 12Cr1MoV steel plate is widely used in the manufacture of various parts of high temperature and high pressure boilers, such as pipes, joints, flanges and support structures.
5, in short, 12Cr1MoV steel plate is a kind of high-performance steel, with excellent mechanical properties and corrosion resistance, suitable for high strength, high temperature, high pressure and corrosive working environment. It has a wide range of applications, including nuclear power plants, petrochemical equipment, power and boiler manufacturing. With the continuous progress of science and technology, 12Cr1MoV steel plates will be applied and developed in more fields.
