Also Sprach sgenn :
"stainless steel" isnt all that resistant to sea water and infact only
resists corrosion by growing a passive layer of oxidation
This process cannot occur under water where there is no oxygen.
Where there is no oygen pitting and deep corrosion will occur
To make matters worse most stainless steel work hardens and becomes brittle
if flexed regularly

Thanks, ya saved me a bunch of typing. Anyone who thinks that stainless
steel is the perfect material should google for "Crevice Corrosion"
