Key Features:

• Corrosion Resistance: The high chromium content (more than 10.5% and less than 30%) in ferritic stainless steels creates a stable oxide at the surface with a strong tendency to protect against oxidation and corrosion, especially when exposed to mildly corrosive environments.
• Magnetic Nature: The magnetic classification of ferritic stainless steels is also relevant for applications requiring such properties owing to the crystal structure, which is of body-centered cubic crystal structure (BCC), in contrast to austenitic stainless steels, which are non-magnetic.
• Thermal Conductivity and Cost-Effectiveness: Ferritic steels demonstrate superior thermal conductivity over other stainless steels and are otherwise less expensive owing to lack of nickel, a metal that goes a long way in aiding resistance to stress corrosion cracking.

Architectural applications of ferritic stainless steels are very important. Their applications in the automotive industry include exhaust systems and decorative trims. Ferritic steels are selected here because of their corrosion resistance and relatively low price. In appliances and kitchen equipment, ferritic steels provide a clean finish compatible with hygienical use. In building and construction, especially architectural cladding and roofing, ferritic steels are applied utilizing both their magnetic properties and weather durability.
