The investigation was carried out to study the effect of surface grinding on chloride induced stress corrosion cracking (CISCC) of austenitic stainless steels 304 at ambient temperature condition. The U-bend tests with thickness 13 mm as per ASTM G 30 were used to investigate the effect of surface grinding on chloride induced stress corrosion cracking (CISCC) of austenitic stainless steel 304 in a corrosive atmosphere containing sodium chloride at ambient temperature. At a high level of tensile

The experimental results recommend that develop a proper metallurgical fabrication criteria, specification, and procedures for pressure vessels to avoid a recurrence in future.
