J55/K55 are lower grade than N80, L80, P110 or T95, so they are a cheaper option material and widely used in non corrosive oil well installation without high strength requirement.Groups of GradeGroup 1: All casing and tubing in Grades with H, J, K, N and RGroup 2: All casing and tubing in Grades with C, L, M and TGroup 3: All casing and tubing in Grade PGroup 4: All casing in Grade Q J55 and K55 are similar material in chemical composition and mechanical properties, especially J55 has lower minimum tensile requirement and lower elongation, others specifications are same like heat treatment methods, NDE test, Charpy Impact test, hydrostatic test.J55/K55 minimum yield strength: 379-552 Mpa;J55 minimum tensile strength: 517 Mpa, elongation ≥ 19%;K55 minimum tensile strength: 655 Mpa, elongation ≥ 15%.
