Question Spring Newbie 2006/4/18(Tue) 14:19

Nice to meet you. I’m studying spring steel, but I don’t have the stress-strain diagram of spring steel (SUP10). Could you provide me any materials?

Thank you for writing to us!
On the left hand side is the general stress-strain diagram of SUP10 (after heat treatment).
In addition, Young’s modulus of SUP10: E is 206000N/mm^2.
