Hot Rolled Steel & Cold Rolled Steel - Difference & Advantages

The half-products are then fed to cold reduction mills. The metal is rolled to the thickness of 0.5…3 mm in case of mild steel and 0.5…5 mm in case of stainless steel. The material is cooled by the use of oil which also acts as a lubricant during the rolling process. As the metal sheet gets thinner between the rolls, its speed increases.
