Ferrite former

Ferrite formers are elements that are added to liquid steel in order to ensure that ferrite is still in the mixed crystal after cooling at room temperature . The ferrite area in the iron-carbon diagram is expanded by raising the A1 temperature and reducing the pearlite growth rate.

The following elements expand the ferrite area homogeneously: Cr , Mo , V , Al , Ti , P , Si , Be . The following elements stabilize the ferrite through heterogeneous limitation of the austenite area: Nb , Ta , Ce , Zr .

As a rule of thumb, the most important ferrite formers can be arranged ( Cr Al Ti Ta Si Mo V W ) so that they sound like a Russian name when pronounced: "Craltitasimovw"
