Abstract

Sensitization and deformation have previously been implicated in the stress corrosion cracking (SCC) susceptibility of Type 304 stainless steel (SS) in oxygenated water. However, Type 304L SS, with reduced carbon content, is expected to be resistant to sensitization effects. The current work evaluates the SCC response of two dual certified Type 304/304L SSs after a sensitization heat treatment. It is shown that other material factors, namely boron content and delta ferrite stringers, can lead to sensitization and subsequent SCC even in L-grade materials.
