STRESS-CORROSION PROPERTIES OF HIGH-STRENGTH PRECIPITATION-HARDENING STAINLESS STEELS IN 3.5% AQUEOUS SODIUM CHLORIDE SOLUTION

Abstract

The plane-strain fracture toughness K(Ic) and stress-corrosion threshold K(Iscc) have been determined for the following high-strength, precipitation-hardening steels: 17-7 PH (RH 950, TH 1050), PH 15-7Mo (RH 950, TH 1050), AM 355 (SCT 850, SCT 1000), AM 362 (H 900, H 1000), AM 364 (H 850, H 950), 17-4 PH (H 900, H 10000, 15-5 PH air melted and vacuum melted (H 900, H 1000), PH 13-8Mo (H 950), and Custom 455 (H 950). Correlations of K(Iscc) with service performance, smooth-specimen test data, and chemical composition are discussed.
