S-N Curve for 420 Stainless Steel
S-N Curve for 420 Stainless Steel
(OP)
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 knowing if 420 Stainless is among the materials in the atlas. If anyone has access to this text, I would appreciate a response as to whether such a curve exists for 420SS before I spend over $200 on a copy.

RE: S-N Curve for 420 Stainless Steel
Martensitic 420SS is commonly used in the annealed form as forgings and obviously can be heat-treated to a wide range of hardnesses (i.e strengths). Since fatigue strength and the UTS are related, you can see why there is unlikey to be a universal fatigue curve for "420SS".
Nevertheless, I'll wait to be corrected...

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.

1. SA 335-GR P91 pipe this is a high chrome alloy with a 9Cr,1Mo,1V
to
2. Din #17240 UNS#42200 material 1.4923 ( I think this stuff is pretty similar to a 420 SS)
Any advice would be greatly appreciated....
