Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Predecessor	Application temperature [°C]
1.2162 (DIN EN ISO 4957 : 2018-11)	1.2162	DIN EN ISO 4957 : 2018-11	Supersedes DIN EN ISO 4957 : 2001-02	Valid	Germany	21MnCr5	≤ 200	1)
1) Remark: 21MnCr5 is a case hardened steel. It achieves surface hardnesses of approx. 60 HRC in carburized condition. Application when required high surface hardness and ductile core. It is suitable for die typing and burnishing. Application: small and medium forms for processing of thermo and and thermosetting plastic, construction parts with high surface hardness and high strength.
