There are many grades of Stainless Steel. The most common in industry are 304S31 and 316S11. These are good quality stainless' but it will corrode in sea water if you leave it in long enough. It doesn't actually rust, like carbon steel, instead it turns into a powder.
In the industry I used to work in, we used to use a number of exotic steels which are much more resistant to sea water attack. 6Mo (Avesta), Inconell, Hastelloy are but a few.
