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 material is ideal for chemical processing, petrochemical, and seawater equipment applications.
Key Features
Excellent resistance to chloride stress corrosion cracking
High thermal conductivity and low coefficient of thermal expansion
Superior resistance to pitting, crevice, and general corrosion
High impact strength and mechanical properties
Material Standards
ASTM/ASME: A240 - UNS S32750
EURONORM: 1.4410 - X2 Cr Ni MoN 25.7.4
AFNOR: Z3 CN 25.06 Az
Applications
Oil and gas industry equipment
Offshore platforms, heat exchangers, and process water systems
Chemical process industries, vessels, and piping
Desalination plants and seawater piping systems
Mechanical and structural components requiring high strength
Power industry FGD systems and scrubber systems
Technical Specifications
Alloy 2507 provides exceptional performance in demanding environments. The material offers excellent corrosion resistance and mechanical properties, though it is not recommended for prolonged exposure above 570°F due to potential toughness reduction.
