MATERIALS - 4340 STEEL - STRESS CORROSION AND EFFECTS OF BANDING LITERATURE SURVEY, PART 1. STRESS CORROSION

Abstract

High strength alloy steels, such as 4340 and 4335 are susceptible to stress corrosion cracking. It is generally agreed by authorities on the subject that the underlying cause of stress corrosion cracking is the marked electrochemical difference in grain bodies and grain boundaries. There is conflicting opinion on how corrosion and stress (tensile) cause the phenomenon to occur. X-ray diffraction appears to be an excellent nondestructive test method for determining stress corrosion cracking susceptibility of met l alloys. Indications are that shot-peening followed by coatings (paints or platings) anodic to the substrate to be protected is an acceptable procedure for prolonging the time before stress corrosion cracking starts in a susceptible metal alloy.
