Tensile test, fracture toughness test, and stress corrosion cracking (SCC) test were conducted in order to evaluate the effect of thermal aging on the mechanical properties and SCC crack growth rate of shielded metal arc weld (SMAW) and gas tungsten arc weld (GTAW) of type 316L stainless steel. Thermal aging at 350 oC induced a moderate increase of ultimate tensile strength in both the welds, and the value of GTAW was higher than that of SMAW. The resistance to ductile crack extension of aged welds was lowe...
