Abstract This paper describes the performance properties of a new 95 ksi minimum yield strength, oil well casing grade designed specifically to resist hydrogen sulphide stress corrosion cracking, SSCC. The new grade, Soo-95SS, demonstrates NACE Tensile threshold values greater than 90% specified minimum yield strength, SMYS, and NACE Bent Beam values in excess of 12.7 x 104 psi. The new Soo-95SS grade also exhibits superior collapse and notch toughness values.
