what are the different grades of stainless steel?

Stainless steels can be defined as a ferrous alloys that contain more than 11% chromium and are resistant to general rusting in mild atmospheric conditions.

They are generally subject to non-uniform attack in chloride containing environments with crevice corrosion and pitting attack being common on many alloys.

Due to the high rate of localized attack that occurs at the start of the attack, the incubation time for attack is often a more significant measure of corrosion resistance than penetration rates.

Stainless Steel are usually classified based on their composition in:

Austenitic Stainless Steel
Martensitic Stainless Steel
Ferritic Stainless Steel
Super Austenitic Stainless Steel
Duplex Stainless Steel
