High-hardness laser hardening can be done quickly!
**Conventional Issues** In high-frequency hardening, the V-shaped surface of the inner diameter within the hardening range becomes over-hardened, resulting in significant distortion after heat treatment and exceeding dimensional tolerances. Although distortion correction was attempted, the risk of cracking was high due to the over-hardened V surface, making correction impossible. **Advantages of Laser Hardening** With laser hardening, it is possible to harden only the surface of the V-shaped area to a high hardness. Additionally, since only the surface is hardened and the interior of the workpiece remains unhardened, the distortion after heat treatment can be kept to a very small level. **Specifications** Dimensions: Φ326×Φ289×T4 Material: S45C Hardness: HRC58 Depth: 0.3mm

Company information
Fujikou Shuhou Industry Co., Ltd. was established in 1958 in Sakai City, Osaka Prefecture, starting with the heat treatment of large bearings. Since then, we have expanded our operations to cover a wide range of industrial machine parts. In December 2008, we began contract processing for laser heat treatment, and in January 2012, we quickly took on laser cladding, continuing to this day. Our expertise in partial heat treatment of metal components spans from large items to precision parts. We have also obtained ISO 9001 certification and have become a certified factory in various industries, continuously striving for improvement in technology and skills through relentless effort and a spirit of reform. As a result, we have earned the trust of our customers across various industries with our high quality and technical capabilities. Moving forward, we aim to accurately respond to the diversifying and advancing needs of our customers, and with our two pillars of high-frequency heat treatment and laser heat treatment, we aspire to contribute, even in a small way, to the advancement of Japanese manufacturing, working together as a unified company.
