Duplex material

Duplex from Special Piping Materials. Duplex stainless steel is a very useful metal that is used the world over. It gets its name from the fact that it consists of two different grades of metal. Essentially, Duplex is a Fe-Ni-Cr alloy that has a two-phase ferritic-austenitic stainless-steel microstructure when it is at room temperature Duplex, rostfritt stål. Tvåfasad blandstruktur med typiskt innehåll på 55 % ferrit och 45 % austenit. Hög kromhalt (Cr), medelhög nickelhalt (Ni), i regel lite molybden (Mo) samt låg kolhalt (C). Korrosionsbeständigheten är oftast mycket bra mot punkfrätning,. Stainless steel: 276 is a group of iron-based alloys that contain a minimum of approximately 11% chromium,: 3 a composition that prevents the iron from rusting, as well as providing heat-resistant properties.: 3 Different types of stainless steel include the elements carbon (from 0.03% to greater than 1.00%), nitrogen, aluminium, silicon, sulfur, titanium, nickel, copper, selenium, niobium.

1.4462 / AISI 318 LN is a duplex austenitic-ferritic chromium-nickel-molybdenum stainless steel. | 1.4462 belongs to the DUPLEX-family. This grade has a good resistance against pitting and stress corrosion cracking. Unique combination of corrosion resistance, resistance to stress corrosion cracking , high tensile and yield strength As the material cools to room temperature, about half of the ferritic grains transform to austenitic grains (islands). The result is a microstructure of roughly 50% austenite and 50% ferrite. The duplex structure gives this family of stainless steels a combination of attractive properties Duplex Stainless Steel. Duplex stainless steels are Fe-Ni-Cr alloys consisting of ferritic-austenitic microstructure at room temperature.
