摘要: An austenitic, stainless steel alloy consists essentially of, in weight percent, about: C 0.030 max, Mn 2.0 Si 1.0 P 0.05 S 0.02 - 0.05, Cr 16.0 20.0, Ni 9.8 14.0, Mo 3.0 Cu 0.8 1.5, N 0.035 up to about 0.75 percent of an element selected from the group consisting Ti and Cb, balance is iron, wherein Cb not more than 0.1 when a (5 x %C) z (10 %C). The provides unique combination machinability, corrosion resistance, formability, mechanical properties.
