PRODUCT DETAILS

16MnCr5 hot rolled steel round bars information

16MnCr5 steel are alloyed case hardening engineering steels for parts which require core tensile strength of 800 – 1100 N/mm² and good wearing resistance. It is an engineering material typically used to manufacture piston bolts, camshafts, levers and other vehicle and mechanical engineering components.
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.
