    Cast iron during solidification of the liquid, metal structure of the phenomenon of residual stress.(internal stress: material internal forces attract or repel each other, each other)
   Is usually used in highway, internal stress does not produce any problems.
But in the racing game there will be a long time continuous high temperature, will be affected by the residual stress, repeated stretching and contraction of particles in the metal structure, resulting in brakeplate deformation or cracking.In order to release internal stress, reduce structure equalization, deformation, cracks, so the need for heat treatment process.
