Ferritic Stainless Steels get their name because these alloys share the same structure as iron, when at room temperature. These alloys have a minimum Chromium content of 11%, low Carbon levels and contain no Nickel. Despite the lack of Nickel, they still provide fair corrosion resistance and stress corrosion cracking hesitance, as well as good formability. Whilst not as popular as Austenic Alloys, Ferritic Alloys comparatively possess better engineering properties. Furthermore, without Nickel, they provide a lower cost option to manufacturers. Increasing the Chromium levels can improve corrosion resistance, however, these alloys have low work hardening rates. Unlike other alloys, they do not develop high strength from cold working and remain magnetic in all tempers.
Nonetheless, Ferritic Stainless Steels are the ideal solution for high volume applications, particularly in domestic environment where moderate corrosion resistance is acceptable. Application include hinges and stays in the UPVC window hardware industry, domestic appliances such as washing machines, cutlery and kitchen utensils. Ferritic Grades can also be found in a range of Automotive applications, including exhaust systems and trims.
