Literature is reviewed on the effect of nickel in low alloy steels on their resistance to hydrogen stress cracking. The greatest portion of literature pertains to H2S environments since there is a controversy in the petroleum industry as to the effect of Ni. Addition of greater than 1 % Ni to carbon and low alloy steels is considered to be either detrimental or of no effect in an alloy's resistance to hydrogen stress cracking. This review should provide a starting point from which more organized studies can be performed to evaluate the true effect of Ni on hydrogen cracking resistance.
