Annealing is a type of heat treatment that alters the physical properties of metals. Annealing helps to increase the ductility of metal and reduce its hardness making the material easier to work. In metals, you would typically anneal an item to increase its machinability or remove residual stresses that can occur in the steel.
Shearing is a metal fabricating process used to cut straight lines on flat metal stock. During the shearing process, an upper blade and a lower blade are forced past each other with the space between them determined by a required offset.
A process of pulling a strip of metal beyond its yield point to permanently change the shape of the strip to make it flat. If you have an edge wave, the concept is to stretch the shorter fibers in the center of the strip so that they will match up in length with the center buckle. If the strip is consistent in length across the width of the strip, you have created flat steel. The tension leveling process is a combination of elongating the strip and bending the fibers over a series of work rolls. Tension leveling will eliminate edge wave and center buckle as well as correct excessive crossbow and coil set.
