Keywords:Stainless steel weld, SCC growth rate in high temperature water, Temperature dependence, Effect of thermal aging, Effect of water chemistry

To investigate effect of temperature and thermal aging on SCC behaviors of stainless steel welds, SCC growth measurement were performed in oxygenated high temperature water with 2900 ppm B. As a result, temperature dependence of the 316L weld was indicated Arrhenius type. And the SCC growth rate was increased after aged at 400℃x20kh.
