Introduction

Overview

Ferritic steels are high chromium (10.5% - 27%), magnetic stainless steels with a low carbon content and little to no nickel content. With the increase of chromium content, its corrosion resistance, toughness and weldability improve correspondently. Its resistance to chloride stress corrosion is superior to other types of stainless steel. The common ferritic grades are Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28 and the like.

Features of Ferritic Stainless Steel

Ferritic stainless steel features high corrosion resistance and oxidation resistance due to its high chromium content, but its mechanical properties and machinability are poor. It is widely applied to acid-resistant structures with little stress and is used as anti-oxidation steel. This steel type can resist the corrosion of atmospheric, nitric acid and saline solution. It features high temperature oxidation resistance and small thermal expansion coefficient. It can be used in nitric acid and food factory equipment, and can also be used to produce parts working at high temperature, such as gas turbine parts.
