Susceptibility of Steels containing Cr, Ni, and Mo in H2 S Environments

The HIC susceptibility of steels containing Cr, Ni, and Mo under stress and hydrogen diffusion was been investigated by electrochemical methods. As the content of alloying elements increased, the apparent hydrogen diffusion        coefficient (D) and threshold hydrogen permeation rate (Jth) for hydrogen embrittlement decreased. Hydrogen content (Co) in the steel in NACE […]
