Jul 25, 2019 · For these applications, a higher level alloy such as 2205 Duplex Stainless or Incoloy® alloy 825 could be a better solution. 2205 Duplex Stainless Duplex stainless steel is called Duplex because it combines both austenitic (ex. 304 and 316 Stainless) and ferritic (ex. 430 Stainless) phases of stainless steel together in a 1 to 1 ratio.
254 SMO ® Super Austenitic Stainless Steel Bar UNS S31254. 254 SMO ® stainless steel bar, also known as UNS S31254, was originally developed for use in seawater and other aggressive chloride-bearing environments. This grade is considered a very high end austenitic stainless steel; mainly comprised of between 19.5% and 20.5% chromium, 17.5% to 18.5% nickel, 6% to 6.5% molybdenum 825 - Rolled Alloys, Inc.825. Incoloy 825 is a nickel-base alloy generally similar to Alloy 20 in aqueous corrosion. It has useful resistance to boiling sulfuric acid up to 40% concentration, to 60% concentration at 176°F and in all concentrations to 150°F. Alloy 825 is stabilized annealed at the mill to
AL-6XN Super Alloy (AL6XN / UNS N08367) offers exceptional resistance to chloride and crevice corrosion, pitting and stress corrosion cracking from acidic, alkaline, and salt solutions. Lean more about the properties, advantages, and specifications of this super-austenitic stainless steel used in Alloy 20 Stainless Steel - Penn StainlessAlloy 20 (UNS N08020) is an austenitic, nickel-iron-chromium based super alloy with additions of Copper and Molybdenum which provide resistance to hostile environments, pitting, and crevice corrosion. It is also stabilized with Columbium to minimize carbide precipitation during welding.
Alloy 825 is an austenitic nickel-iron-chromium alloy also defined by additions of molybdenum, copper and titanium. It was developed to provide exceptional resistance to numerous corrosive environments, both oxidizing and reducing. With a nickel content range between 38 46%, this grade exhibits pronounced resistance to stress corrosion cracking (SCC) induced by chlorides and alkalis. The Alloy 825, UNSN08825, 2.4858, Nickel Alloy Steel, China Alloy 825, UNSN08825, 2.4858. A nickel-iron-chromium alloy with additions of molybdenum and copper. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. The alloy is especially resisitant to sulfuric and phosphoric acids.
Nov 02, 2020 · Likewise, ferritic stainless steels are considered to possibly resist cracking depending on composition but also have temperature limitations. Alloys with higher Ni content such as the super austenitic stainless steels tend not to crack in Cl-environments. Alloy 825 is Corrosion Resistant Metals Materials Selection Guide Stainless Steel. Duplex stainless steels have a two-phase microstructure of austenite and ferrite grains. This structure gives these materials a combination of attractive properties, including strength, ductility, and corrosion resistance. Alloy 2507 super duplex, ferritic-austenitic stainless steel is well-suited for service in highly
