Ferritisch
Ferritic refers to a class of steels that have a body-centered cubic (BCC) crystal structure at room temperature. This structure is known as ferrite. Unlike austenitic steels, which have a face-centered cubic (FCC) structure, ferritic steels are typically non-magnetic and cannot be hardened by heat treatment, though they can be strengthened by cold working.
The ferritic phase is stable at higher temperatures in plain carbon steels, but it persists down to
However, ferritic stainless steels have limitations. They tend to be less ductile and tougher than austenitic
