Ferritic Stainless Steel

Ferritic stainless steel is a type of chromium alloy that has ferritic structure at elevated and room temperature with body-centered cubic crystal structures. It has a chemical composition consisting of C≤0.02% and Cr 10.5%~32% and cannot be hardened by heat treatment. Ferritic stainless steel is used in comprehensive applications with excellent general properties, and is taken as a kind of primary nickel-saving stainless steels.
