Duplex 2205 Stainless Steel Coil, ASTM A789, 1500mm Width, Marine Grade
Duplex 2205 Stainless Steel Coil is a premium-grade material designed for industries requiring exceptional resistance to chloride-induced corrosion, high mechanical strength, and durability in aggressive environments. Compliant with ASTM A789, this duplex (austenitic-ferritic) steel coil combines the advantages of both austenitic and ferritic stainless steels, delivering 2x higher yield strength than standard 316L grades. With a standardized width of 1500mm and thickness ranging from 0.5mm to 12mm, it is ideal for marine, offshore, and chemical processing applications. The 2205 alloy’s balanced microstructure ensures resistance to stress corrosion cracking, pitting, and erosion, making it a top choice for seawater systems, oil rigs, and coastal infrastructure.
