Note
The synergistic effect of high hardness by high level quenching and anti-corrosive treatment that does not deteriorate the material boasts excellent durability.When carburizing and nitriding heat treatment is applied to steel materials, it is very difficult to maintain high-precision dimensions because of the different expansion and contraction rates.Sunstar applies a special heat treatment process using its own facilities and technology.
