Abstract

An austenitic stainless steel having the following composition, in percent by weight (wt.-%): C equal to or less than 0.06, Si 0.1-1, Mn 3-5, Cr 20.5-23.5, Ni 11-15, Mo 1-4, Nb 0.50-0.70, N 0.40-0.60, P equal to or less than 0.050, S equal to or less than 0.005, optionally W equal to or less than 3, optionally Co equal to or less than 0.50, optionally V equal to or less than 0.30, optionally Cu equal to or less than 0.30, optionally B equal to or less than 0.005, optionally Al equal to or less than 0.25, optionally one of Ca or Mg equal to or less than 0.05 or REM equal to or less than 0.5 balance consisting of Fe and normally occurring impurities; wherein the composition fulfils the criterion [wt.-% Mo]+2*[wt.-% W]≥3.
