13 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 tubular 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. JFE LION™ is the latest development in the JFE Steel premium connection gas tight series. Designed and proven to provide full pipe body performance in all pressure and axial load combinations. JFE LION™ has been tested and validated according to ISO 13679: CAL IV 2002, ISO/FDIS 13679:2011 and API 5C5 CAL IV 2017 procedures for testing casing and tubing connections. JFE LION has been designed and validated to the latest industry standards to meet the needs for critical well loads, including HPHT applications.
