EN 1.7131 Steel 16MnCr5 Material
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.
The following tables show material 16MnCr5 datasheet and
specification including chemical composition, mechanical
properties, etc.
