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 semi-finished casting products, such as slabs, blooms, and billets.
Hot-rolled metals generally have little directionality in their mechanical properties and deformation induced residual stresses.
Hot-rolled mild steel seems to have a wider tolerance for amount of included carbon than does cold-rolled steel, and is, therefore reduces workability.
