Question Spring Newbie 2018/6/11(Mon) 16:41

Could you show me the S-N diagram of the piano wire (specifically SWRS62A) and hard steel wire (specifically SWRH62A)?

Spring Newbie, thank you for posting!!!
Please refer to here for the durability limit diagram of piano wire and hard steel wire.

I do not have the diagram for SWRS62A or SWRH62A, but how about using the fatigue limit diagram of JIS B2704 for your reference?

Thank you!!!
