Martensitic and duplex steels are increasingly used in the oil and gas industries when high C02 environments are encountered. Nevertheless, very often the field conditions make traditional 13% Cr steel insufficient due to its limited corrosion resistance and the duplex being too expensive. This paper is aimed at evaluating the performances of new 95 ksi grade and new 110 ksi grade supermartensitic 13Cr-5Ni-2Mo steel for sweet and slightly sour environments. Mechanical properties at room temperature and high temperatures. Sulfide Stress Cracking (SSC) and Stress Corrosion Cracking (SCC) resistance, and localized and weight loss corrosion resistance have been investigated on both modified 13% Cr, traditional 13% Cr and duplex 22% Cr and 25% Cr. Suparmrtensitic 13Cr-5Ni-2Mo proved to be an interesting alternative to the traditional CRAS for use as Oil Country Tubular Goods (OCTG) in typical North Sea environments (high chloride, high temperature, high CO2 wells containing H2S) with improved corrosion resistance properties. Keywords: oil Country Tubular Goods, Martensitic Steels, Superrnartensitic Steels, Duplex Stainless Steels, High Strength, Sulfide Stress Cracking, Stress Corrosion Cracking, Sweet Environment, Sour Environment, Carbon Dioxide, Hydrogen Sulphide.
