Ferritic stainless steel is an exceptionally durable and low-maintenance material with far lower life cycle costs than carbon steel and is 100% recyclable.
Compared with carbon steel, ferritic stainless steel has all the advantages of stainless steel: corrosion resistance, low life cycle cost and long service life. In addition, compared with similar steel types, austenitic stainless steel, its advantages do not stop at its low cost. In fact, ferritic stainless steel is superior to austenitic stainless steel in many properties.
The unique “ace” properties of ferritic 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 (compared with austenitic stainless steel, oxide scale is less likely to form on the surface);
Ferritic stainless steel has high thermal conductivity (heat conduction is more uniform than austenitic stainless steel);
Ferritic stainless steel containing the stabilizing element niobium has good creep resistance (the strain under long-term stress is smaller than that of austenitic stainless steel);
Ferritic stainless steel is easier to cut and process than austenitic stainless steel (cutting of austenitic stainless steel requires special tools and high-power machinery, resulting in greater tool loss);
During cold forming, the springback tendency of ferritic stainless steel is much smaller than that of austenitic stainless steel;
The yield strength of ferritic stainless steel is higher than that of 304 stainless steel (comparable to carbon steel);
Ferritic stainless steel is less prone to stress corrosion cracking.
