Abstract
Cr– Mn– N stainless steels have a cost and strength advantage over conventional Cr– Ni stainless steels. In this study microstructure and mechanical property of hydrogen-charged 18Cr10Mn-0.4N was compared with 18Cr10Ni austenitic stainless steel. This is the first such study for 18Cr10Mn– 0.4N austenitic stainless steel. Electron microscopy was used to compare the deformed microstructure of the uncharged and hydrogen-charged specimens. The results are discussed in view of the current knowledge on hydrogen embrittlement. The 18Cr10Mn– 0.4N steel suffered higher embrittlement mainly because it absorbed moref hydrogen.
