Rolled Steel Stretcher Leveling Services
Obtain flat, stress-free material for your fabrication processes with stretcher leveling services from Alliance Steel.
Stretcher leveling is a process that stretches material sufficiently to exceed the yield point in all its fibers, equalizing internal trapped stresses. This activity produces material that stays flat even after laser cutting, notching, punching, or subsequent shearing operations. Eliminating post-cutting stress springback can make additional processes like welding and forming easier, unlike temper passing which is a process that applies a massive amount of pressure, compressing the steel. In temper passing, two rolling pins travel down the length of the plate/sheet and squeeze out the internal stress.
Stretcher leveling uses a series of E-Drive Levelers to flatten and reduce the crossbow (curvature) before it continues to the stretcher. At the stretcher, clamps grab 40 feet of material and apply 2 million pounds of force; uniformly stretching the material past its yield point. Stretcher leveling can remove all internal stress, eliminating the risk of post-cutting spring back, unlike temper passing.
