nanoMAG™a stainless steel combines "extremely high strength" and "excellent soft magnetic properties" through our proprietary grain size refining technology. It is five times stronger than electromagnetic soft iron, so it can also be used for applications such as rotor cores, which are subjected to strong centrifugal force due to high-speed rotation.

Non-Magnetism
Fatigue Properties
Precipitation/Age Hardening
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.

Precipitation/Age Hardening
SUS631 is the most typical precipitation hardening type steel that can be heat treated to increase hardness while retaining the excellent performance of 18-8 stainless steel.
From the softest solution-treated to the hardest full hard rolled, depending on the processing and application, it is possible to have a strength second only to high-carbon martensitic quenched materials by applying various heat treatments.
In the solution heat-treated state, more than 30% elongation allows for strong processing such as drawing.
Please note that the material is weakly magnetic in the solution heat-treated state, but becomes quite strongly magnetic after precipitation hardening treatment.
This material is hard to obtain due to its relatively small distribution volume, and most of the materials distributed in stock sales are 3/4H finish. However, we can provide from the softest material in solution heat-treated condition (A material) to the hardest material with full hard finish (EH) per your use and processing method in small lot.
TOKKIN supplies a variety of stainless steels for springs as specified in JIS G4313.
Please refer to this page for the features and comparison of each grade of stainless steel for springs.

Precipitation/Age Hardening
The solution heat-treated state (austenite phase) of SUS631 is soft and can be processed in various ways, but requires two or more heat treatments of martensitization and precipitation hardening to increase its strength.
Because SUS632J1 is always in martensitic phase with or without solution treatment, it can be strengthened with only one precipitation hardening heat treatment.
Solution heat-treated or cold rolled finish can be selected, Rolling finish provides higher strength, but not as high as that of SUS631.This steel grade exhibits strong magnetism in all states.
Solution heat-treated materials, although a martensitic phase, can be lightly processed because of its low carbon content and toughness.
Also, because there is little variation in strength at welded portion, it is sometimes used in applications where welding is involved, such as steel belts.

TOKKIN™ 350 is a Cr-Ni-Mo stainless steel. In solution heat-treated and annealed conditions, it boasts excellent workability and high strength by heat treatment.
Compared to other precipitation hardening stainless steels, the addition of Molybdenum provides superior corrosion resistance and oxidation resistance, and the absence of Aluminum and Titanium provides good weldability. It also has excellent yield strength and cyclic fatigue strength, and is used for bellows, diaphragms, actuation valves, etc. which require long life under cyclic stress.
