The steel contains (in wt.%): 0.01-0.08 carbon, 0.1-1 silicon, 5-11 manganese, 15-17.5 chromium, 1-4 nickel, 1-4 copper, 1 x 10<-4>-20 x 10<-4> sulfur, 1 x 10<-4>-50 x 10<-4> calcium, 0-0.003 aluminum, 0.005-0.1 phosphorus, 5 x 10<-4> boron, 0.01 oxygen, and iron and unavoidable impurities the remainder. Preferably, the steel contains (in wt.%): 0.01-0.05 carbon, 0.1-1 silicon, 5-11 manganese, 15-17.5 chromium, 1-2 nickel, 2-4 copper, 1 x 10<-4>-10 x 10<-4> sulfur, 1 x 10<-4>-10 x 10<-4> calcium, 0-0.001 aluminum, 0.005-0.1 phosphorus, less than 0.01 oxygen, and iron and unavoidable impurities the remainder. The steel may also include 0.01-2% Mo. |
