Product Description
- 21CrMoV5-11 is an alloy structural steel, belongs to pearlitic type heat strength steel, can work at about 530 degrees for a long time, mainly used in petrochemical, coal conversion, nuclear power, turbine cylinder, thermal power and other harsh conditions, corrosive medium occasions, such as: boiler, reactor, heater, steam generator, etc. 21CrMoV5-11 (1.8070) Chemical Element Content (%) 21CrMoV5-11 (1.8070) Mechanical properties 21CrMoV5-11 is a type of steel, also known as super alloy. Its chemical composition contains Cr, Mo and V elements, giving it excellent wear resistance and high temperature strength. The material is widely used in the manufacture of mechanical parts that work at high temperatures, such as bearings and gears for generators and gas turbines. This is because in the environment of high temperature and pressure, 21CrMoV5-11 shows thermal stability and creep resistance is very outstanding, can withstand high strength stress. In the manufacturing process, conventional cooling methods are not sufficient to achieve the ideal strength and toughness. Therefore, it is usually necessary to use water quenching or air quenching to ensure that the material has the best performance. This step also makes 21CrMoV5-11 material very hard and can obtain good toughness. In addition, 21CrMoV5-11 material also has excellent thermal fatigue properties. Usually, metal materials at high temperatures will gradually lose part of their strength and properties due to prolonged exposure. 21CrMoV5-11 can continue to maintain its original high strength and toughness, without metal fatigue and brittle fracture problems.
