Super Duplex Stähle

S32760 • 1.4501 • TPS-Technisuperduplex TSD2507

Datasheet

UNS S32760 - 1.4501 is a super ferritic-austenitic grade with high mechanical properties and superior corrosion resistance. Besides the ferritic-austenitic structure, S32760 has an excellent resistance to pitting and crevice corrosion and is therefore particularly suitable for sea water applications and for process systems on offshore platforms, respectively in all situations where there is a risk of stress corrosion. The high tensile properties are twice comparing with TP 316L stainless steel. The service range is between - 50°C up to + 275°C.
