摘要：
A high strength and elongation stainless steel with a hardness of at least HV is formed of a duplex structure comprising 20% to 95% by volume of martensite having an average grain diameter of not more than 10 .mu.m, with the balance being essentially ferrite, the steel including, by weight, up to 0.10% C, up to 2.0% Si, up to 4.0% Mn, up to 0.040% P, up to 0.010% S, up to 4.0% Ni, from 10.0% to 20.0% Cr, up to 0.12% N, more than 0.0050% to 0.0300% B, up to 0.02% O and up to 4.0% Cu, and optionally contains up to 0.20% A1, up to 3% Mo, up to 0.20% REM, up to 0.20% Y, up to 0.10% Ca, and up to 0.10% Mg, with the balance being Fe and unavoidable impurities.
