EN 10216-2 X11CrMo5 Introduce
EN 10216-2 X11CrMo5 is a European-made alloy steel grade composed of a range of chemical elements, primarily carbon, manganese, and chromium. The steel's increased strength, wear resistance, thermal stability, and ductility make it ideal for machining highly precise components such as castings, forgings and tubes. EN 10216-2 X11CrMo5 is often considered a "high machinability" steel due to its high strength-to-weight ratio and excellent machinability.
Smelting temperature:1437°C - 1666°C
Application:Pressure steel - Technical delivery conditions - Part 2: Non-alloy and alloy steel tubes
