### Rolling (metalworking)Wikipedia

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. When using circular mils the formula for the area of a circle becomes begin matrix A= d 2 left( 1 right) end matrix Where A is the area of the circle in circular mils and d is the diameter in mils.
