"Partial high-strength steel" high-frequency hardening
This is a steel material that achieves multiple strengths with a single bar of steel. By using high-frequency quenching, only the areas that require high strength and high durability can be made to have high strength.
In conventional heat treatment using furnaces, it was difficult to apply heat to the entire steel material while only treating the necessary parts. However, by utilizing high-frequency induction heating (IH) to selectively harden only a portion of the steel (enhancing strength and durability), we have achieved multiple strength levels with a single steel rod. By placing high-strength sections in areas that require structural integrity and low-strength sections in other areas, it is possible to control damage and reduce material usage. Using this technology and product, we have started selling high-strength rebar placed in column-beam joints, named "Double Stark®," which contributes to damage control in structures, reduction of rebar quantity, improved workability, and comfortable living spaces. *In 2018, we received the "Super" Monozukuri Parts Award and the Lifestyle-Related Parts Award.
