Annealing is a heat treatment process that involves heating a material to a high temperature for an extended period and then gradually cooling it. The ultimate goal of this process is to soften the metal and improve its ductility. Annealing is particularly used as a process to achieve the softness of materials. Annealing for process and stress relief is used to negate the effects of cooling. In other words, the aim is to soften the metal and increase the ductility of work-hardened materials. Internal stresses are caused by plastic deformation processes, such as uneven cooling during machining, cutting, welding, or casting, or by phase transformations. Warping and distortion occur when internal stresses are not relieved. Annealing removes these stresses when the affected areas are heated to the recommended temperature and held for a sufficient amount of time, followed by slow cooling to room temperature. 【Common Issues】 During heating and cooling, there exists a temperature gradient between the outer and inner parts of the metal. If the temperature change is too great, this temperature gradient can cause internal warping or, in the worst case, cracking. *For more details, please download the PDF or feel free to contact us.*
