To help you find effective ways to relieve stress we rounded up 15 affordable stress relief products that are perfect for busy caregivers. Steel stress relief executed properly. The stress relief process is performed by heating in an oven as seen in figure 1 or furnace to a temperature for steel wire below the lower critical temperature ac 1 and holding at that temperature. The material is then typically cooled at a slow controlled rate so as to avoid adding any other internal stresses to the material.

Stress relief is a process in which a material is heated to a specific temperature for a specific amount of time to reduce the internal forces acting on the material. Cast materials with low ductility or with geometries that include stress risers can increase the probability of cracking during the heating portion of the stress relief cycle. For many alloy steels little or no stress relief occurs at temperatures less than approximately 500 f 260 c while approximately 90 of the stress is relieved by 1000 f 540 c. The maximum temperature for stress relief is limited to 55 f 30 c below the tempering temperature used after quenching from the hardening process.

Unlike normalizing or annealing stress relieving does not change the metal s chemical mechanical properties. Using modern temperature controlling equipment the experts at hi tech steel are able to generate the very specific heating and cooling rates required to relieve and minimize the introduction of new stress. A stress relief operation is typically used to remove internal residual stresses that have accumulated in the material. For steel stress relief to be done properly exact heating and cooling rates need to be used.
