The 10.125″ 79.29# 13CRM-110 VAM SLIJ-II R3 casing is manufactured from Modified 13 Chrome (13CRM), a quenched and tempered martensitic stainless steel engineered for improved corrosion resistance in sweet (CO₂) environments with chloride exposure. Designed to perform at temperatures up to 350°F, this alloy offers enhanced strength and pitting resistance compared to standard 13Cr, making it suitable for deeper wells with elevated pressures and temperatures. Paired with the high-performance VAM SLIJ-II connection, this casing delivers strong sealing integrity and mechanical reliability. Note: For sour service or environments with high chloride concentrations, higher-grade alloys may be more appropriate.
