UNS S31803 2205 Plate Sheet Strip Coil:

UNS S31803 2205 Plate Sheet Strip Coils are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. When duplex stainless steel is melted DIN 1.4462 Duplex Steel Plates solidifies from the liquid phase to a completely ferritic structure. 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.

UNS S31803 Duplex Steel Sheets & Coils are about twice as strong as regular austenitic or ferritic stainless steels. As with all stainless steels, corrosion resistance depends mostly on the composition of the stainless steel. For chloride pitting and crevice corrosion resistance, their chromium, molybdenum and nitrogen content are most important. Duplex Steel UNS S32205 Coils have a range of corrosion resistance, similar to the range for austenitic stainless steels, i.e from Type 304 or 316 (e.g. LDX 2101©) to 6% molybdenum (e.g. SAF 2507©) stainless steels. These 1.4462 Sheets are available in variant shape, size, thickness, dimensions, standards, specifications, designations, grades, alloy, etc.
