摘要

PURPOSE:To improve the corrosion resistance in environment contg. neutral salt by adding prescribed percentages of C, Si, Mn, Cr, Ni, Mo, Cu and N. CONSTITUTION:The titled steel consists of, by weight, =0.08% C, 2-4% Si, =2% Mn, 16-20% Cr, 8-13% Ni, 0.3-1.5% Mo, 0.3-2% Cu, 0.05-03% N and the balance Fe with impurities including =0.002% B. In the composition, the value of an equation Ni-bal=Ni(%)+30[C(%)+N(%)]+0.5Mn(%)-1.1[Cr(%)+ 1.5Si(%)+Mo(%)+0.5Nb(%)]+8.2 is restricted to -2.5-+1. The steel has superior corrosion resistance in an environment contg. neutral salt.
