Question Kogure

I would like to know about tempering.
I recognize that the strength etc. of the material will be slightly improved by tempering, but do you know how much it will be improved? Or does it change depending on the shape, etc.? The materials here are SUS301-CSP 1/2H and SUS304-CSP 1/2H. Thank you.

Answer Tokai Spring

Thank you for writing to us, Kogure!

For material SUS304-WPB (Wire diameter φ2), the strength is improved by about 5% according to the attached document (excerpt from a material). Unfortunately, there is no data for SUS301-CSP 1/2H and SUS304-CSP 1/2H, but it is estimated to be about the same.
