Abstract The Hashimoto-Koshiishi model is the predictive mechanistic model for crack growth rates (CGRs) of stress corrosion cracking (SCC). The simplified formula of the Hashimoto-Koshiishi model was developed for the calculation of CGRs of irradiated Type 316L stainless steels (SSs). This study evaluated the applicability of the developed formula to various types of stainless steels by analyzing experimental data of CGRs. The developed formula was determined to be applicable for Type 304L SSs and 316NG SSs as well as Type 316L SSs. On the other hand, the formula was unsuitable for irradiated Type 304 SSs because the mechanical properties and the Cr concentrations at the grain boundaries of Type 304 SSs were different from these quantities for Type 316L SSs.

Chloride Stress Corrosion Cracking

Abstract Overstressed U-bends of Types 304 and 347 stainless steels were exposed to water containing chloride ions to determine the susceptibility of these steels to stress corrosion cracking between the temperatures of 165 F and 200 F. The pH was controlled at 6.5 to 7.5 and 10.6 to 11.2 for the tests. At the high pH, cracks appeared at the edges with little evidence of pitting. At the neutral pH, cracks were found at the edges and associated with pits. Sensitized Type 304 had longer and deeper cracks than annealed Types 304 and 347 in the same exposure time. Conclusion is made that chloride stress corrosion cracking of these steels in the temperature range of 165 F to 200 F is less severe than that experienced at 500 F and that specific conditions are required for corrosion cracking to occur at all. 3.2.2
