Abstract (en)
Austenitic stainless steel strip comprises (by %.wt): 0.025 = carbon = 0.15; 0.20 =silicon = 1.0; 0.50 = manganese = 2.0; 6.0 = nickel = 12.0; 16.0 = chromium = 20.0; molybdenum = 3.0; 0.030 = nitrogen = 0.16; copper = 0.50; phosphorus = 0.50; sulfur = 0.015; possibly 0.10 = vanadium (V) and 0.03 = niobium (Nb) = 0.50, with 0.10 = Nb + V = 0.50; remainder being iron and production impurities, of which the average grain size of the austenite is less than or equal to 4 mu m and the surface has a brilliance greater than 50. An independent claim is also included for the continuous fabrication of the austenitic stainless steel strip.
