From Swagelok Company
SAF 2507 material has found acceptance in many aggressive chloride-containing environments. Typical applications are found in oil and gas exploration, refining and petrochemical processing, pulp and paper processing, seawater cooling, evaporative salt production, desalination, and geothermal wells. In recent years, the offshore oil and gas industry has used these austenitic/ferritic alloys in welded sub-sea and deepwater fluid systems for chemical injection and similar applications. Fully annealed tubing made of Sandvik SAF 2507 offers significant mechanical strength, weight, corrosion resistance, and pressure advantages over 316L, 6 % molybdenum, and other conventional stainless steels due to controlled ferrite content, high nitrogen content, and smaller grain size.
