Ferritic Stainless Steels

Ferritic stainless steels are generally a group of stainless steels which do not contain nickel but contain high chromium (between 10.5% and 30%), carbide-forming elements such as molybdenum, titanium vanadium, and alloying elements that stabilize the ferritic structure.

The high chromium content they generally contain gives ferritics a very high corrosion resistance. The ferritic stainless steels, which have mechanical and physical properties close to those of their close relatives, carbon steels, are magnetic unlike austenitics, cannot be heat treated due to their low carbon content and can be easily rolled. The sole heat treatment which can be applied to this type of steel is annealing. Recently, the extreme price increase and variability of alloying elements, especially nickel, has accelerated the development of ferritics, and new ferritic grades have been developed, which are resistant to corrosion as well as austenitics at low cost, have a wide range of uses and much lower cost. The most widely known ferritic grades are 430 and 442. The structures of ferritics are BCC.
