Product Introduction
Super 13Cr 110 Pipe is a high-performance martensitic stainless steel tubing and casing solution engineered for demanding oil and gas environments. With approximately 13% chromium and enhanced alloying elements such as nickel (Ni) and molybdenum (Mo), this material delivers superior corrosion resistance, high strength, and excellent performance under high temperature and high CO₂ conditions.
Developed to overcome the limitations of conventional API L80-13Cr and 2Cr13 steels, Super 13Cr P110 is widely used in deep wells, ultra-deep wells, and corrosive oil & gas fields.
