ABSTRACT A corrosion resistant austenitic stainless steel alloy and articles made therefrom consisting essentially in weight percent of Image in which nitrogen ranges from a minimum of 0.15 w/o to no more than the amount that can be retained in solid solution, the balance being essentially iron, and the elements being balanced so that cold rolled annealed specimens prepared with a crevice and tested in accordance with ASTM G4B-76 in 10 w/o FeCl3 ? 6H2O at 50 C for 72 hours have a weight loss of less than 0.3 gram. An embodiment that is particularly well suited for making autogenously welded articles, e.g. tubing, for uses requiring exposure to brackish water consists essentially in weight percent of Image in which the balance is essentially iron.
