Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.

A friable grinding wheel has fresh cutting crystals exposed continuously to the workpiece making it the fastest cutting abrasive. Semifriable abrasive grains do not fracture as readily as friable grains. This results in longer grain life during grinding, but semifriable grains do not cut as freely as friable grains.
