Abstract

Failure analysis of fracture of 35CrMo bolt was investigated. It was analyzed by means of morphology and microstructure analysis, chemical composition analysis, hydrogen content analysis, scanning electron microscope (SEM) micro-morphology of fracture surface, electronic differential system (EDS) corrosion products analysis. The results showed that the cause of fracture of 35CrMo bolt was stress corrosion cracking. Working stress of the bolt,H2S in surroundings and the high hardness of the bolt combined caused cracking of the bolt. Suitable heat treatment for the 35CrMo bolt is suggested.
