I have a question. I’m always worried about fatigue limits when it comes to spring design. Is there any S-N curve data for piano wire (SWPA, SWPB), SUS304, SWOSC-V, SUP material, etc.?

Thank you for writing to us, Catshoes!
Unfortunately, we do not have the S-N diagram for SUS material, but we have a fatigue strength diagram for piano wires and oil temper wires, so we will send them to you directly by email!
