Abstract

PURPOSE: To provide the title steel with superior pitting corrosion resistance having a specified compsn. consisting of C, Si, Mn, Ni, Cr, Mo, N, one or more out of V, Nb and Cu, and the balance Fe.
CONSTITUTION: This steel consists of, by wt., C≤0.01%, Si≤2.0%, Mn≤3.0%, Ni 3.0W6.0%, Cr 23.0W28.0%, Mo 1.0W3.0%, N 0.01W0.4%, one or more out of V≤3.0%, Nb≤1.0% and Cu 0.3W2.0%, and the balance Fe except for impurities or further contains B≤0.1% if necessary. This steel is an improved version of 25Cr-4.5Ni type two-phase stainless steel and is provided with high strength without deteriorating the pitting corrosion resistance.
