TDS-1 Description :

TDS-1 is a high-performance ferritic stainless steel with excellent strength, corrosion resistance, and soft magnetic properties.
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 Steel
It 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.

FAQ's of TDS-1 | Soft Magnetic Stainless Steel:

Q: How is TDS-1 soft magnetic stainless steel manufactured?

A: TDS-1 is produced using advanced metallurgical processes, typically involving cold rolling followed by appropriate annealing or tempering steps. Depending on the desired temper, the material may be bright annealed (BA), skin passed (2B), or left as rolled (hard), with strict quality controls to achieve precise thickness and width tolerances.

Q: What are the typical applications for TDS-1 stainless steel?

A: TDS-1 is commonly used in vibration motors, haptic feedback systems, and various consumer electronics components, thanks to its excellent soft magnetic properties and formability. Its versatility also makes it suitable for applications where stability and magnetic response are critical.

Q: When should I opt for a bright or dull surface finish with TDS-1?

A: The choice between bright and dull surface finishes depends on the intended application and aesthetic requirements. Bright finishes (BA) are preferred for visible or decorative parts, while dull finishes suit internal components where glare and appearance are less critical.

Q: Where is TDS-1 stainless steel typically exported or manufactured?

A: TDS-1 is primarily produced, supplied, and exported by manufacturers based in Japan. Their expertise ensures consistency and adherence to high-quality standards demanded by global markets.

Q: What is the recommended process for handling and fabricating TDS-1 steel?

A: TDS-1 can be easily processed using standard forming, cutting, and welding techniques. For optimal results, select the appropriate temper based on your fabrication method-BA for ease in bending and forming, or as-rolled for higher strength needs.

Q: What benefits does Grade SUS430 offer in soft magnetic applications?

A: Grade SUS430 provides a balance of good magnetism, corrosion resistance, and mechanical stability. It is an ideal choice for soft magnetic usages where both performance and durability are required, particularly in precision electronic devices.
