The difference in hardness between the inside and outside is small, and uniform hardness is achieved in the longitudinal direction as well.
Thin and long wire materials such as drills and ejector pins undergo significant deformation during heat treatment, requiring considerable effort to become finished products. Setting up for hardening fixtures and correcting after hardening can lead to increased lead times and costs, and since heat treatment occurs close to the final process, any variation can be critical. Additionally, the demand for faster processing and longer service life has led to higher alloying of materials, which limits heat treatment conditions and makes it difficult to realize the original performance of certain steel grades. NACHI's pre-hardened wire is a high-performance, hardened and tempered wire developed to address the issues and concerns associated with such heat treatment, utilizing the technology and experience gained from high-speed tool steel manufacturing since the founding of Fujikoshi in 1928. 【Features】 ○ Stable heat treatment quality ○ Excellent heat treatment quality For more details, please contact us or download the catalog.
