2507/S32750 /S25073 DIN1.4410 GB/T713.7 ASTM A240M Super Duplex Steel Plate 14*1500*6000mm

MATERIAL DESCRIPTION

All our super-duplex materials are produced by Norsok M-650 Ed.4 and/ or ISO 17782 qualified manufacturers.

Super Duplex UNS S32750 is the most common super duplex grade in the market. UNS S32750 is a duplex especially designed for service in aggressive chloride-containing environments. It has very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength. It is widely used in oil & gas, hydropower, pressure vessels, pulp & paper, structural components and chemical tankers.

Applications

The main applications are for details 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.

Heat Treatment
Solution annealing in the range of 1100°C followed by water quenching.

Weldability
Very good.
