What is Ferritic Stainless Steel and What all are its Applications? Ferritic Stainless Steel is a grade that contains over 12% of chromium and is magnetic, high – chromium steels that have low carbon content. It differs from other forms of steel in two critical regards; its molecular grain structure and its chemical composition. This type is well known for their good ductility, corrosion resistant and stress corrosion cracking. It is commonly used in automotive applications, kitchenware and industrial equipment. Ferritic is the next most widely used type of S.S after Austenitic type. Ferritic is actually defined as straight chromium non-harden class of alloy. Here are some characteristics
High in Chromium Cannot be hardened or strengthened by heat treatment Magnetic Property Good resistance to stress-corrosion cracking Have better engineering property Less Expensive Good ductility and formability Low Thermal expansion High Thermal Conductivity High Oxidation Resistant
Ferritic stainless steels are classified into 400 series, usually with 10% to 30% chromium content, and are more often chosen for their excellent corrosion resistance and elevated temperature oxidation resistance. With greater strength than carbon steels, ferritic provide an advantage in many more applications where thinner materials and reduced weight are necessary, like in automotive emission control systems.
