SAF 2507® Is a registered trademark for Sandvik

This is a xindeda alloy stainless steel designed to feature high strength, resistance to pitting, stress corrosion cracking, erosion corrosion and corrosion fatigue, crevice corrosion and strong weldability.

Super Duplex Applications

Oil and gas industry equipment,
Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems,
Chemical process industries, heat exchangers, vessels, and piping,
Desalination plants, high pressure RO-plants and seawater piping,
Mechanical and structural components, high strength, corrosion-resistant parts,
Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping.

Super Duplex Corrosion Resistance

The high chromium and molybdenum content of Super Duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex also provides excellent resistance to inorganic acids, especially those containing chlorides.

The pitting Resistance equivalent of Super Duplex, calculated by PREN = Cr + 3.3Mo + 16N, will exceed 40 in most material forms.
