Abstract (en)

[origin: EP0446188A1] The invention relates to a high strength vanadium containing stainless steel alloy in which the amounts of the alloy elements have been balanced such that the austenite phase remains stable without being deformed into martensite even at largely extended reductions. The steel alloy should essentially consist of 0,04-0,25 % C, 0,1-2 % Si, 2-15 % Mn, 16-23 % Cr, 8-14 % Ni, 0,10-1,5 % N, 0,1-2,5 % V, and the remainder being iron and normal impurities.
