* A Superduplex stainless steels, very similar to 2507, with PREN ≥ 40 (Note a). Both alloys have very similar corrosion resistance in strong mineral acids and both alloys have the same limiting application temperatures. This Superduplex contains slightly more copper and tungsten. The copper content permits excellent resistance to corrosion in many nonoxidizing and mineral acids like hydrochloric and sulphuric acid. No difference in seawater and other neutral environments. * Seawater systems and applications (subsea manifolds and pipework, diving spheres), oil and gas Industry including sour gas applications, petrochemical industry including PVC strippers, pulp and paper industry (digesters, bleaching equipments), chemical industry including organic acid applications, sulphuric and phosphoric acid plants, trucklorries multipurpose containers.
