EN 1.4410 / SUPER DUPLEX UNS S32750 / F53 / 2507

Super Duplex UNS S32750 is the most common super duplex grade on the market. UNS S32750 is a duplex alloy specifically designed for service in aggressive chloride-containing environments. It offers excellent resistance to localized corrosion and stress corrosion cracking, combined with high mechanical strength. This grade is widely used in industries such as oil and gas, hydropower, pressure vessels, pulp and paper, structural components, and chemical tankers.

The main applications of UNS S32750 are for components with special requirements for high corrosion resistance.

UNS S32750 is characterized by:

• High resistance to stress corrosion cracking in halide-containing environments.
• High resistance to pitting and crevice corrosion.
• High resistance to general corrosion.
• High mechanical strength.
• High resistance to erosion corrosion and corrosion fatigue.
