Steels and alloys withstand aggressive environments
This company offer a full range of stainless steels and alloys (including duplex and super-duplex grades) that can provide reliable corrosion resistance in high-temperature, high-chloride-concentration environments. The alloys have been developed to combine high strength in the solution-annealed condition, with localized corrosion-resistance properties that are said to be better than super-duplex grades. The hyper-duplex grade Sandvik SAF 3207 alloy is especially well-suited for use in tubing, raw-seawater injection systems, aerated seawater environments, downhole applications in oil-and-gas recovery, umbilicals and other applications that require high strength and relatively thin walls combined with improved resistance to chloride-induced corrosion and cracking and high operating temperatures.— Sandvik Materials, Sandviken, Sweden
