Cold Forming :
2205 alloy can be cut and cold formed. However, because of its high strength and hardness, 2205 alloy needs cold forming more than austenitic steel, and because of its high strength, the springback factor should be fully considered.
Heat treatment :
2205 alloy should be annealed at the lowest temperature of 1900 degrees F, then cooled rapidly and quenched by water. This treatment is applied to solid melting annealing and stress relief. Stress relief treatment, if carried out at temperatures below 1900 degrees F, can easily lead to the precipitation of harmful metal or non-metal phases.

Duplex 2205 Stainless Steel Sheet / Plate
The main alloying elements of duplex steel are Cr, Ni, Mo and N. Among them, Cr and Mo increase ferrite content, while Ni and N are austenite stable elements. Some steels also contain elements such as Mn, Cu and W. Cr, Ni and Mo can improve the corrosion resistance. In the chloride-containing environment, its pitting and crack corrosion resistance is particularly good.
