Heat Treating Springs
Heat treatment refers to a process used to prepare materials for precision spring fabrication. This process relieves stress from the metal, which allows it to hold its shape once the spring is formed. The temperature to which the metal must be heated – and the duration for which it must be held at that temperature – varies depending on the material being used. The material is then cooled using a highly controlled process and cooling rate, to ensure that no new residual stress occurs.
