High strength, high durability, and excellent machinability SUS301 spring material.
NK-301ZF is a spring material that achieves high strength and excellent workability while being within the chemical composition range of SUS301 (JIS). It has even higher strength than standard SUS301 and achieves high durability by suppressing non-metallic inclusions in the steel. Additionally, by optimizing the rolling conditions, it exhibits greater ductility than standard SUS301 spring materials, resulting in superior workability.

basic information
NK-301ZF is a spring material that achieves excellent workability and high strength within the chemical composition range of SUS301 (JIS). <Improved Workability> - It has higher elongation than general SUS301, which helps prevent processing cracks. <Fatigue Resistance Characteristics> - Controls steel inclusions that hinder fatigue resistance characteristics, reducing macroscopic non-metallic inclusions. <Compliance with JIS Standards> - There are no changes to the chemical composition. <High Strength> - It is a high-strength material that can aim for a hardness of HV580 or higher, making it ideal for applications that require long-term repeated durability.
