(10) Compatibility of cold work-treated JPCA steel and its TIG welding with flowing Pb-Bi

Abstract

Corrosion test of cold work-treated JPCA steel and arc welding material using tungsten inert gas (TIG) method was carried in flowing Pb-Bi at 450°C for 1000 hours. The results showed that slight penetration of Pb-Bi accompanied by some superficial pitting corrosion occurred for the cold work-treated JPCA steel. As for the TIG welding material, slight penetration of Pb-Bi and superficial erosion were observed.
