CL Hann offers in house sub harmonic vibratory stress relief.
Stop unwanted material distortion from unbalanced machining & weld stresses!!
The Technology – Sub harmonic vibrational stress relief solves the problem of reducing residual stress in materials. Mill produced products (hot or cold finished) have linear residual stresses forced into their products (roll pressure) that is balanced when the product is used in it’s stock shape. Unbalanced metal removal begins to shift the balance causing unwanted distortion. In weld fabrication the thermal contraction of unbalanced welding causes unnatural tensioned stress forces that will release during final machining or natural aging of the fabrication.
Benefits and Results – Sub harmonic vibratory stress relief is able to affect dimensional stability and overall stress reduction. A benefit to the VSR process is that it doesn’t alter the metallurgical tensile condition of the material (unlike thermal S/R which reduces the T condition of nonferrous metals, the softened metal slows machining times and has poor finishes. Also with VSR there is no material discoloration, process distortion or scaling. Near absolute stability can be achieved on billet plate material by a second VSR treatment after rough machining the material or on a finish machined component.
