NAC’s product is IT Wire (induction tempered steel wire) which is high strength wire rod widely used for general industrial spring manufacturing, including automotive suspension springs. NAC’s IT Wire is categorized as Oil Tempered (furnace heating/oven heating) wire for its mechanical properties; however, NAC’s advanced and unique production system uses electric power instead of gas as heating energy source and water instead of oil for hardening. (Non-Pollution System). From a raw material steel wire rod to the finished steel wire rod product, it is manufactured under perfect quality control by the latest facilities with automatic induction heating system developed solely by Neturen. By using the precise control system for heating and cooling, the wire can get high strength and toughness at the same time.
