Astm A790 Super Duplex 2507 UNS S32750 Stainless Steel Strips
2205 Code Plus Two and 254 SMO are registered trademarks of Outokumpu Stainless, Inc. The impact strength is also high. Alloy 2507 is not recommended for applications which require long exposures to temperatures above 570ºF 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
Standards : ASTM/ASME.. A240 - UNS S32750 EURONORM .. 1.4410 - X2 Cr Ni MoN 25.7.4 AFNOR............ Z3 CN 25.06 Az
Corrosion Resistance : General Corrosion The high chromium and molybdenum content of 2507 make it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. 2507 also provides excellent resistance to inorganic acids, especially those containing chlorides. In dilute sulfuric acid contaminated with chloride ions, 2507 has better corrosion resistance than 904L, which is a highly alloyed austenitic steel grade specially designed to resist pure sulfuric acid. Stainless steel of type 316L (2.5%Mo) cannot be used in hydrochloric acid due to the risk of localized and uniform corrosion. However, 2507 can be used in dilute hydrochloric acid. Pitting need not be a risk in the zone below the borderline in this figure, but crevices must be avoided.
