UNS S42000 | Datasheet

13 Chrome Applicable Environments13 Chrome L80, UNS S42000, is a quenched and tempered martensitic stainless steel used for corrosion resistance in sweet (CO2) and mildly sour (H2S) environments up to 300°F. Commonly used as downhole tubulars, components, packers, and other subsurface equipment, it is included in API 5CT as Group 2, Grade L80, Type 13Cr. Its controlled yield strength and hardness comply with NACE MR0175.

This grade is best suited for mildly corrosive conditions as pH, chlorides, temperature, and H2S may limit its use. NACE MR0175/ISO15156 Table A.19 provides a recommended limit of 1.5 psi partial pressure H2S with pH ≥3.5.
