| Abstract: | The stress corrosion wa s one of lim iting factors in the lifetime of pressur e vessels.The stress corrosion lead to e mbrittlement cracking and destroy the pr essure vessels.The formation conditions and character of stress corrosion fractu re for pressure vessels was summarized.S o me measures were proposed to prevent or c ontrol stress corrosion by selecting mat erials,decreasing and eliminating stress ,and or altering condition of pressure v essels used. |
