Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Predecessor	Application temperature [°C]
1.2842 (DIN EN ISO 4957 : 2018-11)	1.2842	DIN EN ISO 4957 : 2018-11	Supersedes DIN EN ISO 4957 : 2001-02	Valid	Germany	90MnCrV8	≤ 200	1)
1) Remark: 90MnCrV8 is an oil-hardening tool steel. It achieves at least 60 HRC in hardened condition. The steel shows favorable dimensional stability and ductility, it is cutting stable. Application: cutting and diecutting tools for sheet thicknesses up to approx. 6 mm, small shear and roll shear cutter also for paper and plastics industry, threading tools, measuring tools and gages, cold burr cuttings, small plastic mold inserts and similar tools.
