Description	TNM-1 is a specially engineered non-magnetic stainless steel developed to maintain extremely low magnetic permeability even after intensive cold working and forming operations. Conventional austenitic stainless steels such as SUS304 and SUS316L are generally regarded as non-magnetic; however, their magnetic permeability increases as the degree of cold work rises due to the formation of strain-induced martensite. This can create challenges in applications where strict non-magnetic performance is required. TNM-1 addresses this limitation through a carefully optimized chemical composition that stabilizes the austenitic structure and suppresses magnetization, even under extremely high processing rates. In addition to exceptional non-magnetic performance, TNM-1 can achieve hardness levels of approximately 500 HV, making it suitable for applications requiring both high spring properties and near-perfect non-magnetism. Soft-temper materials are also available, allowing deep drawing and complex forming operations while maintaining excellent non-magnetic characteristics. Main Features: Exceptional Non-Magnetic Performance Maintains extremely low magnetic permeability even after severe cold rolling, stamping, and forming operations. High Strength and Hardness Achieves hardness levels up to approximately 500 HV, providing excellent spring characteristics and durability. Stable Austenitic Structure Specially designed alloy composition suppresses strain-induced magnetization during processing. Excellent Formability Soft-finished material can be deep drawn and formed into complex precision components. Ideal for Precision Electronics Suitable for applications where magnetic interference can affect performance or measurement accuracy. Medical and Communication Equipment Applications Combines corrosion resistance, strength, and non-magnetic performance for demanding medical and electronic products. TNM-1 is widely used in camera modules, communication equipment, medical devices, indwelling needles, motor components, sensors, and precision electronic assemblies where both high strength and extremely low magnetism are critical requirements. Product catalogs and detailed technical information are available upon request. Material selection support can also be provided to help identify the most suitable non-magnetic alloy for specific application requirements.
