This article describes the different forms of environmentally assisted cracking that can affect low alloy steels and corrosion resistant alloys in the oil & gas industry.
Sulfide Stress Cracking
Corrigendum – Sulfide stress cracking of nickel-containing low-alloy steels
Corrigendum of our paper entitled: “Sulfide stress cracking of nickel-containing low-alloy steels”.
ISO 15156-3 will set new restrictions on UNS S174000 (17-4PH)
This article describes the results of a recent NACE MR0175/ ISO 15156 ballot that imposes stringent maximum allowable stress values.
Sulfide stress cracking of nickel-containing low-alloy steels
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.
Effect of nickel on the phase transformation kinetics of low alloy steels
This posts summarizes the main effects of nickel on the phase transformation of kinetics of low alloy steels.
Hydrogen Embrittlement of Nickel Alloy Steels
This post illustrates a possible sulfide stress cracking mechanisms at the open circuit potential for low alloy steels.
