Stress corrosion cracking (SCC) of Type 304 and 304L stainless steels, Inconel 600, Incoloy 800, and Monel 400 has been studied in water at 315 C, with or without 0.6 ppm Pb and 0.05 or 8 ppm O/sub 2/. Under mill annealed, cold worked (25%) and stress relieved (675 C, 1 hour) conditions, Type 304L, Incoloy 800, and Monel 400 were resistant to cracking, whereas highly stressed Inconel 600 cracked intergranularly. Inconel 600, heat treated at 600 C for 24 hours or more following annealing, was resistant to SCC. The effects of microstructural changes on SCC behavior are discussed. 20 refs.
