Advantages of ferritic stainless steel (400 series stainless steel)

Ferritic stainless steel is magnetic.

Ferritic stainless steel has a low thermal expansion rate (the degree of expansion when heated is less than that of austenitic stainless steel).

Ferritic stainless steel has good high temperature oxidation resistance (the tendency of surface oxidation and spalling is less than that of austenitic stainless steel).

Ferritic stainless steel has high thermal conductivity (ferritic stainless steel conducts more uniformly than austenitic stainless steel).

Ferritic stainless steel has good creep resistance (the strain under long-term stress is smaller than that of austenitic stainless steel).

Ferritic stainless steel is easy to cut and process (the cutting of austenitic stainless steel requires special tools and high-power machinery, causing greater tool loss).

When deformed by cold working, the deformation recovery tendency of ferritic stainless steel is small.

Ferritic stainless steel has a high yield strength (equal to carbon steel).

Ferritic stainless steel has no tendency to stress corrosion fracture.

Ferritic stainless steel has all the advantages of stainless steel: corrosion resistance, low life cycle cost and long life, etc., and low cost.

According to the use environment, purpose, etc., select the appropriate stainless steel
