Austenitic stainless steel to be used hot and of which the chemical composition by weight comprises from 16 % to 25 % of Ni, from 16 % to 18.5 % of Cr, from 0 % to 3 % of Mo, from 0 % to 2 % of Mn, from 1 % to 3.5 % of Ti, from 0 % to 1.5 % of Al, less than 0.1 % of C+N, up to 0.025 % of B, the rest being iron and impurities resulting from the fabrication; the chemical composition satisfies the relations: (0.94xNi - 65xF)/(1 - F)>/=12 and 17</=(1.07 xCr - 1.5 x F)/(1 - F)</=22, with F = 0.0444 x Ti + 0.0777 x Al - 0.0592.
