An austenitic stainless steel for use for high temperature concentrated sulfuric acid which comprises, on weight basis, 0.04 % or less of C, 5 - 7 % of Si, 2 % or less of Mn, 15 - 25 % of Cr, 4 - 24 % of Ni, 0.01 - 1.07 % of Pd and the rest consisting of Fe and unavoidable contaminant materials. By the incorporation of small amount of palladium in a basal austenitic stainless steel containing the essential three elements of Cr, Ni and Si, a superior corrosion resistance against highly concentrated high temperature sulfuric acid is attained.
