Stainless steel that is not easily magnetized even when a magnetic field is applied is referred to as "Non-magnetic stainless steel." Even in austenitic stainless steels such as SUS304 and SUS316L, which are commonly considered non-magnetic, the permeability increases as the cold working rate increases. In order to use the material in a non-magnetic state, there were issues such as keeping the processing rate low and insufficient strength.

This steel type is specifically designed with adjusted composition to maintain non-magnetism even at extremely high processing rates. With an exceptionally high strength of 500 HV, making it ideal for applications requiring both near-perfect non-magnetism and high springiness. Besides, soft-finished material can also be drawn.

We can also help you select appropriate materials besides TNM-1 in accordance with your issues and actual use.

TNM-1 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
