Influence of Fluctuation Frequency on Stress Corrosion Cracking of X70 Pipeline Steel Welding Joint

Qi Sun, Wei Shao, Xing Gang Wang, Cheng Bei Wang

Abstract

Influence of the fluctuation frequency on stress corrosion cracking (SCC) behavior of X70 pipeline steel welding joint was studied in the cathode potential under nearly neutral medium by fluctuant slow strain rate test (F-SSRT). SCC sensitive parts occurs in overheated zone of X70 pipeline steel welding joint under cathode potential nearly neutral medium. SCC crack can be produced from the material surface micro holes and expanding their range up the main stress plane extension, when the load fluctuation frequency increases to a certain degree, SCC crack propagate along 45° maximum shear stress plane.
