Question Seaman

I am selecting a spring that can be mounted on the outside of the SGP20A (φ27.2) pipe which will be used in the temperature of around 100°C is selected.
P482 is appropriate for the height dimension, but is SWP-B material okay to be used in this environment? If the heat resistance of the piano wire is not good, could you recommend a material for compression springs that can be used instead?

Answer Tokai Spring

Thank you for writing to us, Seaman!
The temperature here is close to the temperature limitation of springs made by SWP-B, so I think using SWOSC-V or SUS304-WPB material is better!
