Sulfide Stress Cracking Resistance of High Strength Low Alloy Steels with Varying Nickel Content

Low alloy steels are one of the most commonly used material systems in oil and gas fields as they can be heat treated to appropriate strength levels including higher strengths such as 758 MPa (110 ksi) and 862 MPa (125 ksi) minimum yield strength while providing economical solutions for various oilfield conditions. Higher hardenability of low alloy steels is an important factor to ensure proper heat treatment to higher strength levels and this is typically achieved by addition of elements such as Chromium (Cr) Molybdenum (Mo) Nickel (Ni) etc. in the alloy chemistry. It is also essential to ensure adequate toughness in these high strength steels to reduce risk of brittle fracture. Increasing Ni content in the chemistry of low alloy steel can provide increased hardenability while maintaining good toughness when heat treated to high strengths. However the guidelines of NACE MR0175/ISO 15156-2 currently restrict the maximum Ni content to 1% mass fraction and in general recommend use of Cr-Mo type low alloy steels such as 41XX series in sour (H2S) service. This has generally led to exclusion of low alloy steels containing higher Ni such as 43XX series in sour service. In this paper an effort is made to evaluate the sulfide stress cracking (SSC) resistance of common grades of Cr-Mo and Ni-Cr-Mo steels heat treated to high strength using NACE TM0177 Method A testing. This would also assist when comparing the cracking resistance of high strength low alloy steels with greater than 1% mass fraction Ni content to those which are within this limit.Keywords: high strength low alloy steel Cr-Mo Ni-Cr-Mo sulfide stress cracking (SSC) 1% Nickel content
