1.2842 (DIN EN ISO 4957 : 2018-11) 90MnCrV8 1.2842 DIN EN ISO 4957 : 2018-11 Supersedes DIN EN ISO 4957 : 2001-02 Valid Germany 90MnCrV8 1.1.1 ≤ 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.
