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.
Austenitic Stainless Steel
Austenitic stainless steel is the largest category of stainless
steels, making up about two-thirds of total stainless steel
production. They possess an austenitic microstructure, a
face-centered cubic crystal structure.
This micro-structure is comprehended by alloying steel with
sufficient nickel or manganese and nitrogen to maintain an
austenitic microstructure at all temperatures, ranging from the
cryogenic region to the melting point. Thus, austenitic stainless
steels are none hardenable by heat treatment since they possess the
same microstructure at all temperature environments.
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
