INVESTIGATION OF STRESS-CORROSION CRACKING OF HIGH-STRENGTH ALLOYS

Abstract

Four groups of specimens of vacuum-cast 9%-Ni 4%-Co steel were placed in test. The material was tested at three strength levels attained by double- tempering at 400, 600 and 800 F. Material at each strength level was exposed to four environments: aerated distilled water, aerated tap water, aerated salt water, and 140 F water saturated air. The chemical and physical prop erties of the material are tabulated. Results show that the only failures have occurred in the 140 F water-saturated air environment.
