Abstract:

EFFECT OF VARIOUS CONVENTIONAL HEAT TREATMENT ON STRESS CORROSION RESISTANCE. Report on Material - Stainless Steel - Armco 177 PH, by H. Stier, P. W. Bergstedt, and H. C. Turner. 29 Apr 1959, 10p. incl illus. table Rept. no. 8926-001 Contract AF 336578926 Unclassified report DESCRIPTORS Stainless steel, Corrosion, heets, Heat treatment, Manufacturing methods, Hardening, Sprays, Salts, Sea water, Sand blasting, Fracture Mechanics, Failure Mechanics Elasticity, Hardness, Chemical analytiCAL PROPERTIES, Stresses. Identifiers 17-7 PH Stainless Steel. The stress corrosion resistance of 0.032 and 0.040 inch thick Armco 17-7 PH stainless steel sheet was evaluated under a stress of 0.8 of the guaranteed 150,000 psi minimum yield strength in the presence of Federal S AND R o. 151 AL SPRAY ATMOSPHERE. Material conditioned by RH-1050, TH-1050 and RH-95 heat treatments and strains representative of fabricating steps were examined. Material treated by RH-1050, T -1050 a d RH- HEAT TREATMENTS POSSESSED S RE S CORROSION SUSCEPTIBILITY INVERSELY RELATED TO HARDENING TEMPERATURE. Double hardening treatments reduced the stress corrosion susceptibility but reduced strengths below specified values.
