RE: [PSUBS-MAILIST] 304 stainless

["Daniel Lance" <lanceind@earthlink.net>]

Brian,
304 stainless steel is not suitable for saltwater use . Below water it will
not have a very long service life . Above water if you have it electro
polished you will have a little better luck, BUT there will be periodic
maintenance involved. 316L is your best bet for the marine environment .
