The 9.625″ 53.5# JFE-UHP-17CR-110 JFELION CBR R3 casing is designed for high-pressure, high-temperature (HPHT) applications, offering superior corrosion resistance in sweet (CO₂) environments with moderate chloride levels. Made from 17 Chrome, a quenched and tempered martensitic-ferritic stainless steel, this casing provides enhanced mechanical properties and resistance to CO₂, chlorides, pH variations, and elevated temperatures. The JFELION CBR R3 connection delivers high torque and a reliable seal, making this casing ideal for deep well and offshore operations, where durability and performance are critical in challenging conditions.
