SCC growth behaviors of welds and cast stainless steels were investigated in oxygenated water with 2900ppmB at 320℃ and 290℃. In the case of 316L/308L welds, the temperature dependence were indicated simple 1/T, higher SCC growth rates were observed than that of the oxygenated water at 320℃ with 500ppmB + 2ppmLi.
