Hydrogen stress cracking steel
WebThis study investigates various factors that influence the cold-cracking ratio (CCR) of flux-cored arc welds through Y- and y-groove tests. Factors affecting the CCR include the alloy component, diffusible hydrogen content, microstructure, hardness, and groove shape. In weld metals (WMs; WM375-R and WM375-B) of a low-strength grade, the diffusible … Web@article{osti_6371843, title = {Hydrogen embrittlement and stress corrosion cracking}, author = {Gibala, R and Hehemann, R F}, abstractNote = {This book presents proceedings which give an account of knowledge and understanding of hydrogen embrittlement and stress corrosion cracking from the viewpoints of the authors.
