This 7″ 23# 13CR-80 JFELION R3 casing is manufactured from 13 Chrome (L80 Type 13Cr), a quenched and tempered martensitic stainless steel offering reliable corrosion resistance in sweet (CO₂) and mildly sour (H₂S) environments up to 300°F. Designed for use in wells with moderate chloride exposure, it meets NACE MR0175/ISO15156 standards for sour service applications. The JFELION connection delivers a high-performance gas-tight seal with excellent tensile and compressive strength, making it ideal for demanding casing operations in HPHT and corrosive conditions.
