DESCRIPTION: SS 430 is a corrosion and heat resistant Ferritic Chromium steel. It can be polished to appear similar to Chromium plate. The material is magnetic in both annealed and cold rolled tempers. Lower Chrome and the absence of Nickel result in a lower work hardening rate than Austenitic grades resulting in a lower breaking strength especially when fully cold rolled. Most often used in the annealed (soft) condition this grade has good formability and a moderate corrosion resistance. Unlike the Austenitic grades the Ferritic steels respond strongly to a magnet. When cold rolled and annealed the surface finish is reflective. It is significantly lower cost than the Austenitic grades. Can only be hardened by cold work.
APPLICATIONS: Automotive and domestic appliance trim, domestic sinks, domestic washer drums, floppy disc hub and pressings generally. And heat resistance products, electronic parts, interiors and exterior for architectures, Military industrial applications etc.
