Duplex S32750 Stainless Steel Plate 50.0mm Hot Rolled ASTM EN GB Standard

Duplex S32750 Stainless Steel Plate 3.0 - 50.0mm Hot Rolled NO,1 SS Plate ASTM EN GB Standard

Duplex 2507, is a commonly used super duplex stainless steel. Also sold as Alloy 2507, this alloy is used in situations where exceptional strength and corrosion resistance are in demand. Some of the applications and industries that utilize Duplex 2507 include:

• Chemical process industries
• Heat exchangers, vessels, and piping
• Desalination plants and other saltwater applications
• Power industry FGD systems
• Offshore platforms including fire-fighting systems

The reason Duplex 2507 is utilized is due to its unique properties. On top of its basic corrosion resistance and strength, Duplex 2507 also provides:

• Extreme resistance to uniform corrosion
• Good resistance to inorganic acids/chlorides
• Works with dilute hydrochloric acid
• Improved machinability and weldability
• High impact strength

To be considered Duplex 2507, an alloy it must contain a number of different chemical components including:

• Fe Balanced
• Cr 25%
• Ni 7%
• Mo 4%
• N .27%
• C 0.020%

Our company offers a wide range of forms and sizes of Duplex 2507, all of which meet industry standards such as ASTM, ASME, EURONORM, and AFNOR.


S32750 or Duplex 2507

Duplex 2507 is a super duplex stainless steel developed for applications that demand high strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel.
This high molybdenum, chromium and nitrogen content causes high resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.
Using Duplex 2507 must be restricted to applications below 600° F (316° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.
Duplex 2507 has good mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting weight savings can considerably reduce the overall cost of fabrication.

Applications of S32750 Super Duplex Stainless Steel

Alloy 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
The applications of S32750 super duplex stainless steel are:

• Desalination Equipment.
• Chemical process pressure vessels, piping and heat exchangers.
• Marine Applications.
• Flue Gas Scrubbing Equipment.
• Pulp & Paper Mill Equipment.
• Offshore Oil production/technology.
• Oil and gas industry equipment.
