EN 1.7131 Steel 16MnCr5 Material現(xiàn)貨價(jià)格查詢

EN 1.7131 steel (16MnCr5 material) is an European standard carburized steel (case hardening steel) with good hardenability and machinability. For larger cross-section parts, high surface hardness and wear resistance can be obtained after heat treatment, and low-temperature impact toughness is also high. For specification and datasheet, please see the tables below.

16MnCr5 steel is generally used after carburizing and quenching, and is mainly used for manufacturing gears, worms, sealing bushings and other components.
