The Science of Forming
and oiled,” or HRPO. Some hot-rolled steels measure as thin as 1.5 mm, with 3-5 mm typical for most production mills. Should thinner material or additional processing be required to develop desired properties, the steel hot band is sent for cold rolling. Limited industrial applications exist for stamped aluminum sheet after hot rolling, making the process pri- marily an intermediate step prior to cold rolling.
As the name indicates, cold rolling occurs at ambient temperatures. Thickness reductions of 70 to 90 percent are needed to create targeted properties of the ordered material. This rolling step increases material strength to what is called the full-hard condition, but the material now is too brittle for all but a select few applications. Annealing, or heating the coil above a critical temperature, relieves internal stresses in the sheetmetal. Changing how the steel or aluminum cools from the annealing temperature affect its tensile prop- erties. Calling something “cold-rolled” only reveals some of the processing performed on a coil—it doesn’t narrow down the hundreds of grades that can be produced at steel or alu- minum mills.
Melt chemistry, rolling practice, annealing cycle as well as other processing steps such as coating or leveling all affect the forming and joining properties of sheetmetal grades. Be sure to use terms that your material supplier understands. Otherwise, you might not get what you want... or what you need. MF
