Super Duplex 2507 / UNS S32750 Stainless Steel Pipe DN100 DN200 DN300 Duplex SS Pipe

Super Duplex 2507 / UNS S32750 Stainless Steel Pipe DN100 DN200 DN300 Duplex SS Pipe

UNS S32750 is a super duplex stainless steel designed for applications that demand exceptional strength and corrosion resistance. Super Duplex stainless UNS S32750 is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades.

Super Duplex UNS S32750 is the most common super duplex grade in the market. UNS S32750 is duplex stainless steel specially 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.

UNS S32750 Super Duplex (2507) Features

• Super duplex grade with combination of properties given by austenitic and ferritic structure
• High mechanical strength.
• High resistance to stress corrosion cracking in halide-containing environments.
• High resistance to pitting and crevice corrosion.
• High resistance to general corrosion.
• High resistance to erosion corrosion and corrosion fatigue.
• Good weldability and workability
• Low rate of thermal expansion
• Suggested for applications up to 600° F

S32750 Super Duplex Chemical Composition

The Chemical Composition of UNS S32750 (2507) consists of 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen contents provide excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

S32750 Super Duplex Mechanical Properties

Duplex S32750 possesses excellent mechanical properties. Often a light gauge of S32750 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication.
