21CrMoV5-7 is a low-alloy steel which is widely used in the manufacture of components that are exposed to high temperatures and pressures, such as pressure vessels, steam boilers and turbines in the power generation industry with a working temperature of up to approx. 540°C.

The chemical composition of 21CrMoV5-7 includes chromium, molybdenum, and vanadium. These alloying elements improve the material’s strength, toughness and resistance to high temperatures, making it suitable for use in harsh environments.

The steel is characterized by its high strength and toughness in combination with excellent weldability and machinability. It also has a high creep resistance, which is the ability to resist deformation under high temperatures and prolonged stress.

This material is often heat treated to achieve specific mechanical properties. The typical heat treatment process includes quenching and tempering to improve its hardness, strength, and toughness. The resulting material has a high fatigue strength.

Overall, 21CrMoV5-7 is a reliable and durable material that is widely used in various applications where high strength and temperature resistance are required.
