Abstract

The present disclosure relates to an austenitic stainless alloy comprising in weight % (wt %): C less than 0.03; Si less than 1.0; Mn less than or equal to 1.2; Cr 26.0 to 30.0; Ni 29.0 to 37.0; Mo 6.1 to 7.1 or (Mo+W/2) 6.1 to 7.1; N 0.25 to 0.36; P less than or equal to 0.04; S less than or equal to 0.03; Cu less than or equal to 0.4; balance Fe and unavoidable impurities and to the use thereof and to products made thereof. Thus, the austenitic stainless alloy comprises a low content of manganese in combination with a high content of nitrogen. The present disclosure also relates to the use of said austenitic stainless alloy, especially in highly corrosive environments and to products made of thereof.
