Ferritic Stainless Steel
Ferritic stainless steels are chromium alloys with a low carbon content. They are magnetic and have a good ductility, plus resistance to corrosion and oxidation (they are especially resistant to stress corrosion cracking). However, with the exception of 3CR12, their weld ability is limited which restricts their use to thinner gauges. These stainless steels are cheaper than the austenitic grades, and used extensively in the motor industry.

Austenitic stainless steels
Austenitic stainless steels are chromium and nickel based alloys with very low carbon content. These steels have excellent corrosion resistance, unusually good formability, good weld ability and good mechanical properties at very low and high temperatures. Cold working will also enhance their strength. In addition, these stainless steels are very easy to clean, which enhances their use in hygienic and sterile environments.
