The invention relates to an austenitic high-manganese stainless steel having high strength and ductility. The stainless steel which consists of in weight % 0,03 - 0,1 % carbon, 0,08 – 1,0 % silicon, 14 – 26 % manganese. 10,5 – 18 % chromium, less than 0,8 % nickel, 0,05 – 0,6 % copper, 0,1 – 0,8 % nitrogen and 0,0008 – 0,005 % boron, the rest being iron and inevitable impurities occurred in stainless steels, and the stainless steel is cold deformable utilizing the TWIP (TWinning Induced Plasticity) mechanism. |
