There are more different "stainless" steels than you can imagine, with varying degrees of corrosion resistance. The 300 series steels have probably the best properties in this regard. Look for hardware in 316$$. If you are still experiencing severe corrosion problems with this material, then something besides salt water is at work. Note that even dilute concentrations of HCl will corrode 316 stainless eventually, and stainless is subject to anodic corrosion as well. When in doubt, check the hardware with a magnet; the 316 material is totally non-magnetic. Hope this helps. ByeBye!
