摘要

The thermal aging embrittlement of several austenitic stainless steel welds(ASSWs),E308,E308L,ER316,ER316L welds,were evaluated.The thermal ageing was performed at 343 ℃,375 ℃,and 400 ℃ for up to 20,000 h.After thermal aging,the decrease of tensile ductility and fracture toughness was observed but with different degree.
