Abstract

A corrosion resistant martensitic chromium steel, having a specified carbon/nitrogen ratio and a fine homogeneous microstructure, is new. A novel corrosion resistant martensitic chromium steel has the composition (by wt.) 0.2-0.4% C, 0.15-0.5% Si, 0.15-0.6% Mn, 12.0-15.0% Cr, NOTGREATER 0.28% Ni, 0.05-0.19% N, balance Fe and impurities, the C/N ratio being greater than 2.0.
