Duplex Stainless Steel 2507 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 impact strength is also high. Alloy 2507 is not recommended for applications which require long exposures to temperatures above 570F because of the risk of a reduction in toughness.
Applications 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
