“I use stainless steel 302 and 304 as trimming in a salt water tank, and the salt concentration is around 2500 ppm. The chloride causes the stainless steel to corrode. Are there any powder coatings suitable for my application?”

“I would use a high nickel content stainless steel first. A marine grade stainless steel can be very suitable for your situation. If you really want to powder coat this part, use an epoxy powder coating. This powder is the most resistant to salt water corrosion.”
