Abstract
A joint program was formulated between the Electric Power Research Institute and the General Electric Company to investigate the elements responsible for the intergranular stress corrosion cracking incidents in as-welded Type-304 stainless steel piping the boiling water reactor environment. The specific objectives of this program were to identify and to quantify the effect of the state of stress and the state of sensitization which exists in as-welded Type-304 stainless steel piping on the intergranular stress corrosion cracking behavior of small and large diameter piping systems and to determine the difference in service performance. The results of this 2 1/2-year program and a mechanistic interpretation of the causes of cracking in Typ-304 stainless steel welded piping are presented.Keywords
