"Spring News September Issue" includes trivia about springs: "Heat Treatment"!
September issue of the Spring News delivered every month! Tempering will be done in an electric furnace.
Heat treatment is performed to eliminate distortion after spring forming and to stabilize it. The temperature and time are set according to the material and wire diameter. Previously, we used quenching treatment (heating followed by rapid cooling to harden), but now we perform tempering treatment (technically referred to as low-temperature annealing) in an electric furnace. When piano wire or steel wire undergoes tempering treatment, a thin oxide film forms on the surface, changing it to a blue color. This blue color is referred to as temper color. Please leave the design, estimation, and production of various springs to us. *For more details, please refer to the PDF document or feel free to contact us.
