Description	SUS301 is an austenitic stainless steel grade in which the chromium and nickel content is reduced compared to SUS304, making it easier to strengthen through cold working. Full-hard tempers such as EH (Extra Hard) and SEH (Super Extra Hard) achieve extremely high strength through cold rolling alone, without requiring additional heat treatment. SUS301 is widely used for spring applications and precision components that require excellent durability, fatigue resistance, and elastic properties. Its inherent corrosion resistance allows it to be used in many environments without additional anti-rust plating. Main Features: Excellent Work Hardening Characteristics Easily strengthened through cold rolling and forming processes. High Strength Spring Material Available in a wide range of tempers from 1/4H to SEH, making it suitable for demanding spring applications. Good Corrosion Resistance Maintains the corrosion resistance typical of austenitic stainless steels. Wide Application Range Suitable for electronic components, automotive parts, precision springs, switches, hinges, and industrial applications. We supply SUS301 spring stainless steel materials in accordance with the requirements of JIS G4313 and related standards.
