2507 Super Duplex Steel Plate UNS S32750 DIN 1.4410
Alloy 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications requiring exceptional strength and corrosion resistance. This steel offers excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide superior resistance to pitting, crevice, and general corrosion.
Material Standards
ASTM/ASME: A240 - UNS S32750 EURONORM: 1.4410 - X2 Cr Ni MoN 25.7.4 AFNOR: Z3 CN 25.06 Az
Industrial Applications
Oil and gas industry equipment
Offshore platforms, heat exchangers, and process water systems
Fire-fighting systems, injection and ballast water systems
Chemical process industries, vessels, and piping
Desalination plants and high pressure RO-plant systems
Seawater piping and mechanical structural components
Power industry FGD systems and scrubber systems
Absorber towers, ducting, and high-strength corrosion-resistant parts
Technical Specifications
Alloy 2507 super duplex stainless steel is engineered for applications demanding exceptional strength and corrosion resistance in chemical process, petrochemical, and seawater equipment. The material features excellent resistance to chloride stress corrosion cracking with high thermal conductivity and low thermal expansion. Impact strength is notably high. Note: Not recommended for prolonged exposure above 570°F due to potential toughness reduction.
