Super 13Cr is a martensitic stainless steel that offers high performance and excellent corrosion resistance in oilfield environments containing CO2, chlorides and low concentrations of H2S. It is available in two conditions. A 95 ksi min yield condition that is suitable for limited NACE sour service environments with a maximum hardness of 28 HRC. A 110 ksi version is also available for standard and CO2 oilfield environments. This material is commonly used in downhole completion tools for components such as offset mandrels, packers, and safety valves among other applications.
