Ferritic stainless steel

Sep 30, 2016

Chromium 15% to 30%. Its corrosion resistance, toughness and weldability with the increase of chromium content increased, resistance to chloride stress corrosion resistance is better than other types of stainless steel, fall into this category are Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28 and so on. Ferritic stainless steel because of high chromium content, corrosion resistance and oxidation resistance are better, but poor mechanical properties and process performance, and more for the little acid structure and for the use of antioxidant steel. This kind of steel can resist atmospheric, nitric acid and brine solution corrosion, and has high temperature oxidation resistance, thermal expansion coefficient is small, etc., for nitric acid and food factory equipment, can also be produced at high temperature parts, such as gas turbine parts .
