Abstract

Corrosion-resistant alloy having a hardness of more than 54 HRC consists of (in wt.%):0.40-0.85 C, up to 1.0 Si,, up to 1.4Mn, 16.0-19.0 G, 0.8-1.5 Mo, 0.05-0.2 V, up to 0.18 Ti, 0.12-0.29 N, with the proviso that Ni max is 0.25, Co max. is 0.20, Cu max is 0.25, and Ni + Co + Cu, max is 0.48. The sum of the concn. of C and N is 0.61-0.95. Also claimed is the mfr. of a corrosion-resistant cutting tool.
