TDS-1 | Soft Magnetic Stainless Steel
Overview & Features
It has high magnetic flux density and low coercive force, making it excellent in magnetization, demagnetization, and magnetic shielding properties. It can be used as electromagnetic stainless steel by applying magnetic annealing.
Main features of TDS-1:
(1) Electromagnetic Stainless SteelIt can be used as an electromagnetic stainless steel by magnetic annealing.
(2) Corrosion Resistance
TDS-1 has a better corrosion resistance than SUS430.
(3) Conductivity is nearly the same as 42 Alloy,
The coefficient of thermal expansion of TDS-1 is about half of 42Ni, though the conductivity is the same. Switching from 42Ni can reduce costs by as much as 50%.
(4) Extensive installation experiences with TDS-1 replacing other grades
We have abundant experience of introducing TDS-1 to our customers to replace their current steel grades such as 42Ni, phosphor bronze, SUY, Permalloy, etc.
We can also manufacture foils below 0.10 mm in thickness and in small lots.

Mechanical Properties
Corrosion Resistance
The corrosion resistance is equivalent to SUS304 and higher than SUS430, soft magnetic iron steels, and Permalloy.
In general environments, it can be used without plating or other surface treatment.
Magnetic Properties
Magnetic properties of TDS-1 is as shown in the table below.
By performing magnetic annealing, it has better maximum permeability and coercive force than SUS430, resulting in a high response to external magnetic fields.

Soft Magnetic Materials
Soft magnetic material is easily magnetized when a magnetic field is applied, but returns to its original state when the magnetic field is removed. We also manufacture our original steel grades such as electromagnetic stainless steel with corrosion resistance and extremely high strength.
Stainless Steels
Stainless steel is an alloy of iron (Fe) with at least 10.5% chromium (Cr) and is used in a wide range of applications because it has good properties in terms of corrosion resistance, strength, workability, and heat resistance.
