Resistance To Ferric Oxide Formation

Stainless steel's resistance to ferric oxide formation results from the presence of chromium in the alloy, which forms a passive film that would protect the underlying material from corrosion, and can self-heal in the presence of oxygen. Corrosion resistance can be enhanced further, by:

addition of molybdenum (which also improves resistance to "pitting corrosion")

increasing the chromium content to levels above 11%;

addition of 8% or higher amounts of nickel

Ferritic Stainless Steels

Ferritic stainless steels possess a ferrite micro-structure like carbon steel, which is a body-centered cubic crystal structure, and contain between 10.6% and 27.2% chromium with very little or no nickel. They are magnetic.

This micro-structure is present at all temperatures due to the chromium addition, so they are not hardened by heat treatment. They cannot be strengthened by cold work to the same degree as austenitic stainless steels.
