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