Other elements:-
* A Superduplex stainless steel with PREN ≥ 40 (Note a) It has a very high resistance to localized corrosion in chloride media, stress corrosion cracking, pitting and crevice corrosion, combined with a high mechanical strength. The corrosion resistance is better than 904L and comparable to 6Mo austenitics. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. Usage of Duplex 2507 should be limited to applications below 300°C (600° F). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507. * Seawater systems and applications (subsea manifolds and pipework, diving spheres), oil and gas Industry including sour gas applications, petrochemical industry, pulp and paper industry (digesters, bleaching equipments), chemical industry including organic acid applications, phosphoric acid plants, truck-lorries multipurpose containers, subsea manifolds and pipework.
