2507 Super Duplex . 2507 Super Duplex 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 Duplex Steel Materials 2507 tube DN200 DN800 DEWEI A 25Cr Duplex Stainless Steel - Sandmeyer Steelwith 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 hydro-chloric acid due to the risk of localized and uniform corrosion. However, 2507 can be used in dilute hydrochloric acid. A Guide to Duplex Stainless Steel What is It? - Unified Duplex Steel Materials 2507 tube DN200 DN800 DEWEI Duplex stainless steels get their name from their two-phase microstructure. While exact ratios vary by grade, most duplex steels have a structure that is roughly 50-percent austenite and 50-percent ferrite. This gives duplex stainless many of the perks of austenitic and ferritic families of steel while also minimizing the weaknesses.

Do not mix components of other materials with Alloy 2507 super duplex tubing. Steel bend shoes are required to bend Alloy 2507 Applications of Duplex Stainless SteelWhen Duplex Stainless Steel is melted, it solidifies from the liquid phase to a completely ferritic structure. As the material cools, approximately half of it changes to an austenitic structure. The result is an alloy with a microstructure of roughly 50% austenite and 50% ferrite. Duplex alloys have higher strength and better stress corrosion Duplex Steel Materials 2507 tube DN200 DN800 DEWEI CHALLENGES WELDING DUPLEX AND SUPER DUPLEX HISTORY OF DUPLEX STAINLESS STEEL DSS is not a new material and spans a history of 84 years. The first wrought duplex stainless steels were produced in Sweden in 1930 and were used in the sulfite paper industry. These grades were developed to primarily reduce intergranular
Duplex Stainless Steel , referred to as DSS. In DDS, ferrite and austenite each account for about 50%, and one of them also requires at least 30% stainless steel . The main representative grades are 2205 duplex steel (S32205, Corrosion resistance of duplex stainless steelsOn the other hand Duplex stainless steel 2507 and 2205 provide adequate service in the aq. HCl. Pitting is generally not an issue however crevice attack should be prevented.
