Abstract

Tempered martensitic Type 403 stainless steel suffers pitting corrosion and intergranular stress corrosion cracking in 0. 01 M Na//2SO//4 at temperatures of 75 and 100 C, but not at lower temperatures of 25 and 50 C. Significant sulfur (sulfate) contamination of the passive film from solution was found, but the level of contamination could not be correlated with susceptibility. Nonmetallic inclusions (MnS) and carbide precipitates act as nucleation sites for corrosion pits which in turn give rise to IGSCC.
