EN 1.7131 Steel material 16MnCr5
Steel EN 1.7131 (material 16MnCr5) is a European standard carburized steel (hardened steel) with good hardenability and machinability. For larger cross-section parts, high surface hardness and wear resistance can be obtained after heat treatment, and the low temperature impact toughness is also high. For specifications and datasheet, see the tables below.
16MnCr5 steel is generally used after carburizing and quenching, and is mainly used in the manufacture of gears, worms, seal bushings and other components.
