When using stainless steel 2507 and 2205 to construct the housings of equipment intended for use in seawater, how should the corrosion allowance be determined? Is the corrosion allowance 0? ? ?

Is 2205 suitable for seawater environments?

Both types of duplex steels exhibit better corrosion resistance in seawater than 316L.

If there are no particulates, the corrosion allowance need not be considered. The corrosion rate is approximately less than 0.2 mm per year.

Both of these materials are suitable for corrosion resistance in seawater; the key is to prevent marine organisms from attaching to them
