Duplex 2205 Stainless Steel Coil
Duplex 2205 Stainless Steel Coil is a nitrogen-enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels.
Duplex 2205 Stainless Steel Coil contains molybdenum, chromium, and nitrogen. The addition of molybdenum provides resistance to pitting and crevice corrosion in chloride environments. Chromium improves the corrosion resistance in sulfate environments, whereas nitrogen enhances its resistance to stress corrosion cracking.

2205 stainless steel coil is a popular product among duplex stainless steel coils. Coils made of 2205-grade stainless steel are processed and shaped through different processes such as hot rolling, cold rolling, drawing, and forging. After processing, surface treatments such as cutting, polishing, and passivation are performed to improve its mechanical properties and corrosion resistance.
