ITW® stands for Induction heated, quenched and Tempered Wire, which is our trade name for high-strength spring steel wire that has been high-frequency heat treated
Uniform strength over the entire length and small strength variation between product coils → Helps to suppress shape variation during spring formin
We can also manufacture products outside the standard tensile strength range above. Please consult us separately.
In addition to our SWI series, we also manufacture high-frequency heat-treated spring steel wire of special specifications using SWOSC-B (JIS G 3560) and alloy steel.
Φ3.5~φ17.0
Please consult us for wire diameters other than the above.
