Abstract

PURPOSE:To prevent the stress corrosion cracking of a metastable austenitic stainless steel without deteriorating the characteristics of the base metal by heating the sensitized region formed by welding the steel, in a temp. zone in which carbide is precipitated. CONSTITUTION:When a metastable austenitic stainless steel previously stabilized or treated to precipitate carbide is welded, a sensitized region is formed in the vicinity of a deposited metal. The region is soln. heat treated or heat treated in a temp. zone in which carbide is precipitated while controlling the treating time so that a Cr-depression layer is not formed in the periphery of the carbide. Thus, the region is recovered. Since the base metal was already stabilized or treated to precipitate carbide, it is not affected by the local heat treatment and the characteristics do not deteriorate.
