Hi all, I think someone here might be able to help me... It is recommended by a steel spring wire manufacturer that immediately aftercoiling, the springs should be stress relieved at about 400°C. (750°F.) for 30 minutes. If one doesn't have an oven that can heat something that high, can the springs be heated at a lower temp for less time? or does heat treating not work like this? Any help would be great. Thanks, Lucas.
