Ferritic matrix microstructure

The ferritic matrix microstructure consists primarily of body-centered cubic iron crystals with extremely low carbon solubility, forming the soft, malleable base matrix in specific steels and nodular cast iron. It ensures excellent cold-forming properties as well as high magnetic permeability.

Ferrite is the basic structure of unalloyed and low-alloy steels – soft, tough, and easy to form. When welding, you have to be careful not to let the part get too hot or cool too quickly. Otherwise, martensite forms, the structure becomes hard and brittle, and you get cracks. Especially with higher-carbon steels, that means: let it cool slowly, then the ferrite stays stable and the component doesn't distort.
