Sulfide stress cracking of nickel-containing low-alloy steels

September 29, 2014 by Mariano Iannuzzi

Low alloy steels with a nickel content greater than 1% are not allowed in sour service applications. This paper reviews the effect of nickel on the hydrogen embrittlement performance of low alloy steels.
