The content of chromium, molybdenum and nitrogen in the chemical composition of duplex S32750 provide it with high
resistance to pitting and crevice corrosion in chlorine-containing environment,e.g. sea water.
The low carbon content of 2507 reduces the chance of carbide precipitation during heat treatment, making the steel
resistant to intergranular corrosion.

Duplex S32750 features high mechanical strength (up to 570 MPa) and resistance to stress corrosion cracking. A pitting
resistance equivalent of > 40.0 makes the material resistant to pitting. The S32750 also has a low thermal expansion
coefficient and high thermal conductivity.

Scope of application Super Duples 2507
Super duplex 2507 is recommended for use in aggressive environments: it shows a high level of strength and corrosion
resistance in a large number of organic acids and alkalis. Due to these qualities, the material is actively used for:
pipelines of the chemical industry and seawater desalination plants;
production of heat exchangers and tanks;
equipment for the oil and gas industry;
manufacture of chemical tankers.
Duplex 2507 is approved for use in pressure vessels.
Various products are produced from this alloy according to ASTM standards:
A182 - forged flanges;
A240 - plates, sheets, strips;
A276 - bars;
A314 - bars;
A479 - bars and profiles;
A480 - plates, sheets and strips;
A511 - seamless pipes;
A789, A790 - welded and seamless pipes;
A815 - fittings.
