Corrosion resistance of stainless steel
I need to prevent corrosion on series 400 stainless steel against salt water. I'm thinking about electropolishing. Can anybody help me with this matter or make some suggestion?FlavioStramare Ribeiro

Electropolish will delay the corrosion, but 410 is mostly iron and a little chrome. It has no nickel and will rust, probably in weeks if it is warm and moist with a trace of salt.James Watts

400 series is quite unhappy in salt water. Either use one of the 300 stainlesses, or plate the 400. But if you're going to plate for corrosion resistance, it would seem that you don't really need any kind of stainless to start with.

Electroless nickel has a long history of success fighting corrosion in marine areas. It¥s a good candidate. There are other alternatives like copper-nickel-chrome, tin or even organic finishes that are sprayed and baked.
Good luck.Guillermo Marrufo
