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 33(657)8926) 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.
