Sorry JAB, I do not believe any published S-N Curves exist for 420SS. I've looked in Boyer's Atlas and the ASM handbooks. I feel if they existed, they'd be in one of those references. The closest thing are curves for 422SS, which is a modification of 420SS with additions of nickel, moly...
Thanks,
I did find a copy of Boyer's Altas at our local university library. As you have said, 422SS is in the Atlas, but not 420SS. But tring to convince a manager that one is can be similar to another is sometimes not easy.
Dear rustbuster, because 420SS is commonly used in various hardened conditions, I was hoping an S-N Curve existed which included various curves for various heat treat and tempering temperatures, as is the case for 420SS in the ASM reference. But if it does matter, the condition I'm interested...
I am trying to find an S-N Curve for 420 stainless steel.
I've already checked our ASM Reference, which has S-N Curves for 410 and 422 stainless, but not 420. I've also looked online at the MIL-HDBK-5H, but to no avail. I do not have Boyer's Atlas of Fatigue Curves, but I am interested in...
