I'm not a metallurgist either, but because I've read 100's of liability-case related documents on the properties of stainless steel, I know that 316 is much more resistant to stress corrossion than 304.

The 'L' means low carbon, which is lower than regular 316. From surfing it seems the 'L' is needed if the material will be welded, but not otherwise. 316 is the most resistant to acid - that is the best for salt water exposure. My guess is the 18/3 designation is 18% chrome, 3% moly (max). For some other SS alloys the numbers seem to indicate chrome/nickle content. I have no clue as to where designations like 304 and 316 come from. I either slept through that class or played hookey. Anyone know why? I found some web sites on the subject: http://www.diveweb.com/maritech/features/uw-su99.01.htm http://chemistry.about.com/library/weekly/aa071201a.htm I also found hits for "stainless 316" on surgical apparatus and body piercing web sites as well!
