Ferritic Steel

Definition - What does Ferritic Steel mean?

Ferritic steel is a type of steel that is composed of less than 0.10% carbon. It is magnetic and not capable of hardening through heating.

This grade of steel was developed as a stainless steel group that can resist oxidation and corrosion, specifically stress cracking corrosion (SCC).

Corrosionpedia explains Ferritic Steel

Ferritic steels are known for their elevated chromium and low carbon contents. They are magnetic, ductile and highly resistant to corrosion. This kind of steel is typically used in the manufacturing of industrial equipment, automotive parts and kitchenware.

Due to its nature, ferritic steels cannot undergo hardening or strengthening by heating. But its strength is enough to resist corrosion. However, it can be softened or cold worked through the process of annealing. Although it is not as strong as austenitic metals, its engineering properties are superior. Yet, ferritic metals have weldability limitations, so it is not advisable to use this type of metal in thinner measurements if it is to undergo welding.

Ferritic steels are more affordable because they contain less nickel and chromium. Yet, this does not compromise its usability, as it has a wide range of applications.
