Heat treatment strengthening technology of spring

Heat treatment strengthening technology of spring

1) Maintenance atmosphere heat treatment. In our country, the heat treatment of spring with wire less than 15mm, oil quenched tempering steel wire and toughened steel has adopted maintenance atmosphere heat treatment. Maintenance atmosphere heat treatment can eliminate the appearance of decarbonization and oxidation, improve the appearance quality of the data.

2) Induction heating or maintenance atmosphere induction heating heat treatment. This process is generally carried out on the wire before the coil spring is formed, and some spring factories put the wire data heat treatment and the spring manufacturing together to reduce costs. Induction heating treatment has a good strengthening effect, induction heating speed is fast, help refine the grain and reduce the appearance of decarbonization, can give full play to and improve the strength and toughness of the data.
