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.

This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths.
Applications include the heading of bolts and cap screws and the finishing of cold rolled steel. In cold forming, metal is formed at high speed and high pressure using tool steel or carbide dies. The cold working of the metal increases the hardness, yield strength, and tensile strength. Theory. Before work hardening, the lattice of the material ...

A fresh fracture shows a clear bluish color with a high silky luster and fibrous appearance. Wrought iron lacks the carbon content necessary for hardening through heat treatment, but in areas where steel was uncommon or unknown, tools were sometimes cold-worked (hence cold iron) in order to harden them.
The requirements on the flatness of the plate and sheet products sold by Rolled Alloys vary considerably by the type of product, by alloy, by thickness and by the size of the piece.
