Zusammenfassung:	The invention relates to a low-nickel austenitic stainless steel with high resistance to delayed cracking and the use of the steel. The steel contains in weight % 0,02 - 0,15 % carbon, 7 - 15 % manganese, 14 - 19 % chromium, 0,1 - 4 % nickel, 0,1 - 3 % copper, 0,05 - 0,3 % nitrogen, the balance of the steel being iron and inevitable impurities, and the chemical composition range in terms of the sum of carbon and nitrogen contents (C+N) and the measured Md3o-temperature is inside the area defined by the points ABCD which have the following values Point M
