The UNS S31010 high nitrogen stainless steel provides an excellent combination of high mechanical properties and corrosion resistance even on product thickness larger than 400 mm (15 ¾ in.). In the hot worked and solution annealed condition, this alloy provides 80 ksi minimum yield strength at 0.2 % offset at room temperature (MYS), impact toughness as high as 100 J or higher at -60 °C and corrosion resistance similar to or better than many austenitic stainless steels and Ni-alloys. In order to extend the application of this material, high strength UNS S31010 with 140 ksi MYS has been produced by warm work hardening and cold work hardening. The characterization of high strength UNS S31010 with respect to corrosion resistance is given and discussed in this paper.

Key words: UNS S31010, AF932N, high nitrogen austenitic stainless steel, high corrosion resistance, high strength
