The grade of SS you find in hardware from the DIY stores for bolts, screws, and washers is 304. It will definintely rust...it will just longer than steel without nickel mixed. 316 SS has steel, nickel and molybdenum mixed. The downside of any SS is that is relatively brittle compared o traditional steel.


Stainless Steels Chromium-Nickel
304 stainless steel has a high resistance to corrosion and lends itself to many types of fabrication, making it one of the most widely used forms of stainless steel used today.

Stainless Steels Chromium-Nickel-Molybdenum
316 stainless steel has a high resistance to many chemical corrodents and marine atmospheres. 316 stainless steels are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels. 316/316L stainless steels also offer higher creep, stress-to-rupture and tensile strength at elevated temperatures. 316 are also well suited for fabricated or formed applications.
