| Zusammenfassung: | An austenitic stainless steel containing the following alloy elements expressed in percent by weight: C 0.02-0.10; Cr 17.6-19.0; Ni 3.5-4.5; Mn 10.5-12.5; Cu 1.5-3.0; Si 0.15-0.60; N 0.25-0.40; S = 0.01; P = 0.03, and optionally Mo 0.2-1.0 and B 0.001-0.003, the remainder being, unavoidable impurities apart, iron. The invention also relates to a process for preparing rolled steel sections having the above-indicated chemical composition and the rolled sections thus obtainable. In addition to reduced production costs, the steel of the invention exhibits mechanical properties higher than those of conventional AISI 3XX steel products and, production costs being substantially equal, analogous formability and corrosion resistance higher than that of conventional AISI 2XX steel products. |
