Ferritic grades

Ferritic grades

Magnetic ferritic stainless steels are easy to form and machine, come in a wide range of attractive surface finishes, and support superior product design.

Our lower-chromium ferritic grades are widely used in applications such as automotive exhaust systems, while our intermediate-chromium grades are popular among the world's leading household goods manufacturers.

In containing little or no nickel, our ferritics are very attractive from the price stability point of view.
Our latest innovation in ferritic steel grades is new high-chromium ferritic grade Core 4622 (EN 1.4622) which is particularly suitable for façades, elevators catering and automotive industry.

Product properties

Ferritic stainless steels have good mechanical properties, sitting broadly in the middle between the other stainless steel families. They typically have higher yield strength than austenitic stainless steels. Elongation and forming properties are equivalent to those of high-strength carbon steels.

Modern ferritic stainless steels are readily weldable with conventional welding methods, including:

  • Shielded metal arc welding (SMAW, MMA)
  • Gas tungsten arc welding (GTAW, TIG)
  • Gas metal arc welding (GMAW, MIG/MAG)
  • Plasma arc welding (PAW)
  • Laser welding
  • Resistance welding
  • High frequency welding (HF)

Corrosion resistance

Ferritic grades offer a wide range of corrosion resistance properties from non-severe conditions inside the home to rough outdoor conditions. At the high-end, ferritics surpass even some austenitic grades in corrosion resistance. 

The corrosion resistance of stainless steel is determined more by chemical composition than by austenitic or ferritic atomic structure. Hence chromium content is the key ingredient also in the corrosion resistance of ferritic stainless steels.
