Corrosion of Stainless Steels in the Immediate Vicinity of the Weld Metal

Abstract

The type of intercrystalline corrosion known as ‘knife-line attack’ is related to structural changes in stabilised stainless steels after superheating to the solldus temperature, with subsequent reheating to the critical temperature. A special study has been made of dendritic carbides found on grain boundaries after superheating, and of the corrosion of titanium carbide in nitric acid. Methods for reducing the susceptibility of stabilised steels to knife-line attack are of limited application.
