Duplex 2507, which is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. This alloy is designed for applications which require exceptional strength and corrosion resistance;
examples include applications in chemical processing, 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 nickel
levels provide excellent resistance to pitting, crevice, and general corrosion.Duplex 2507 (UNS S32750) in sheet, sheet coil, plate, plate coil, round bar, processed flat bar and tubular products
Common Applications of 2507
- Oil and gas industry equipment
- Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems
- Chemical process industries, heat exchangers, vessels, and piping
- Desalination plants, high pressure RO-plant and seawater piping
- Mechanical and structural components, high strength, corrosion-resistant parts
- Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping
