The effect of carbon on hydrogen embrittlement in stable

Abstract The effect of carbon on hydrogen embrittlement in stable austenitic stainless steels is investigated by adding either 0.02 or 0.1 wt.% C.During deformation,planar slip is pronounced and fine dislocation structures develop,which is followed by mechanical twinning in both steels.After hydrogen pre-charging,the alloy with higher carbon is more susceptible to hydrogen embrittlement.Technical Reference on Hydrogen Compatibility ofThe role of martensite on hydrogen embrittlement in austenitic stainless steels has not been hydrogen and tested in high-pressure hydrogen gas,Figure 3.1.1.1; the absolute ductility [21].In comparison,type 316 alloys with lowerTechnical Reference on Hydrogen Compatibility ofThe magnitude and temperature dependence of hydrogen permeability is very consistent between studies on various solid-solution Ni-Cr alloys and values reported for austenitic stainless steels (Figure 2.1).The diffusivity of hydrogen in the solid-solution Ni-Cr alloys appears to be slightly greater than for austenitic stainless steels.
