This is a pre-hardened material that achieves the highest level of straightness and roundness in the industry through high-frequency heat treatment.
We manufacture and sell pre-hardened materials with excellent straightness by performing high-frequency heat treatment on various special steel materials, including structural steel, die steel SKD61, high-speed tool steel SKH51, and stainless steel. In response to customer requirements, we deliver products in a form that is closer to a finished product, including centerless grinding, cutting to product length, center hole processing, and chamfering. 【Features of Netsuren Pre-Hardened Materials】 - We deliver straight materials even for steel types with significant heat treatment warping or thin diameter materials, eliminating (or greatly reducing) the need for correction processing. (Example: SUS440C φ2.0x2200L warping below 30μm) - Due to short-time quenching with high-frequency heating, almost no decarburization layer occurs on the surface, allowing for reduced grinding allowance in subsequent processes. (Process shortening, resource conservation) - We also accommodate centerless grinding, providing materials with industry-leading roundness and cylindricity. (Example: AISI4150 roundness below 2μm, cylindricity below 3μm) - Not only surface hardening but also through hardening is possible. - We can also accommodate hollow materials.

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 non-polluting. 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, returning to the founding principle of "Technology of Netsuren," and will continue to make unceasing efforts to be of greater service to society in the coming era.
