Abstract

This study makes use of the latest fundamental concepts on Hydrogen Embrittlement, HE, to try to understand and resist better this phenomenon. Three different steel grades have been studied: C-Mn steels, 3.5 Ni steel and 2.25/3 Cr steels, both in thee laboratory and industrial heats. Laboratory heats have been developed so as to study particular groups of HE parameters. Since recent ideas on HE ("Trap Theory of HE") have shown that different test techniques may yield different results, many techniques have been used: F% test, disk rupture test, fracture mechanics, progressive cracking techniques, permeation and mass spectrometry, electronic microscopy. Many conclusions have been drawn. Finally, practical rules are given concerning the steelmaking and use in hydrogen of the steels studied.
