stainless steels contain larger amounts
of Cr which stabilizes the ferritic phase.
Ferritic stainless steels are highly corrosion
resistant, but far less durable than austenitic
grades and cannot be hardened by heat
treatment. They contain between 10.5%
and 27% chromium and very little nickel,
if any. Typical applications may include
appliances, automotive and architectural
trim (i.e., decorative purposes),
as the cheapest stainless steels are found
in this family (type 409).
