It is a high-strength spring steel wire with a small diameter (3.5mm to 5.0mm) for high-quality cold forming, using high-frequency induction heating.
Netsuren "ITW(R)" imparts the necessary mechanical properties to carefully selected materials through high-frequency quenching and high-frequency tempering, and conducts flaw inspection using eddy current testing along the entire length, as well as quality assurance through monitoring of heat treatment temperatures. It is manufactured on a per-coil basis, ensuring uniform wire diameter and strength throughout the entire length. Additionally, the variation between product coils is kept to a minimum.

Company information
Netsuren successfully commercialized and industrialized IH (Induction Heating) technology for the first time in Japan in 1946 (Showa 21). This IH technology is a double eco (Ecological and Economical) technology that uses clean electricity as its heat source, making it environmentally friendly and pollution-free. As a pioneer in this field, Netsuren has developed highly original products in addition to contract heat treatment processing, based on the know-how accumulated since its founding and its high level of technical and development capabilities, bringing transformation and contribution to various industries. The fact that Netsuren exists today and can contribute to society, even in a small way, is thanks to your unwavering support and warm patronage. To enhance corporate value through harmony and coexistence with customers, business partners, shareholders, society, and employees, Netsuren aims to remain a company with a dignified presence in the future. We will return to the founding principle of "Technology of Netsuren" and continue our tireless efforts to be of greater service to society in the coming era.
