Abstract

Based on an explosion case of stainless steel waveform expansion joint happened from wet H2S stress corrosion cracking, this article carries out analy si s that the accident caused by the brittle fracture of low stress is closely related to cold work hardening of austenitic stainless steel and massive deformation martensite. And it also suggests that the solid solution treatment to austenitic stainl ess steel will be favorable to mitigation of stress corrosion cracking occurrence and reduction in stress corrosion crack growth rate, then the modification suggestion to related regulations was given.

Keywords

Austenitic stainless steel, Deformation martensite, Cold work hardening, Solid solution treatment, Stress corrosion.
