(1) Ferritic stainless steel:
It is that steel when properly heat treated and finished, resists
oxidation and corrosive attacks from corrosive media. Ferritic stainless steels contain
12–18% chromium, 0.15 to 0.2% carbon besides iron and usual amounts of manganese
and silicon. The steels are stainless and relatively cheap. They are magnetic in nature.
Structure of these steels consist of ferrite phase which cannot be hardened by heat

treatment. These steels are actually iron-chromium alloys and cannot be hardened
by heat treatment. Such type of steel is utilized in manufacture of dairy equipment
food processing plants, etc.
