ABSTRACT:
An austenitic stainless steel immune to stress-corrosion cracking and intergranular stress-corrosion cracking in both the annealed and cold worked condition. The steel consists essentially of 0.005 - 0.08% carbon, 0.01 - 0.04% nitrogen, 16.0 - 20.0% chromium, 8.0 - 10.0% nickel, and 3.5 - 5.5% silicon, to form a microstructure consisting of 7 to 45 volume % delta ferrite in an austenitic matrix. The steel is further characterized by exceptional resistance to pitting corrosion and intergranular attack and good weldability and hot and cold workability.
