4340 Steel SN Curve Where R=0 1

[dcopps]

I am looking for an S-N Curve for 4340 Steel where R=0. I can find several with an R value of -1 and others, but have not found the R=0 curve.

The data you want is in MIL_HDBK_5J...

Heres a link:

Just look for the handbook, be carefull this is a 70MB PDF, of some 1700pgs, dont send it to a printer by mistake.

Nick, et al.,

FYI, MIL_HDBK_5J has been cancelled and replaced with the "Metallic Materials Properties Development and Standardization (MMPDS)," DOT/FAA/AR-MMPDS. Fortunately, we had both Release G of MIL-HDBK-5 and MMPDS here in-house. The latter contained 13 or so graphs of S/N curves for 4340 steel plotted with the R factor set at 0 and -0.1--just what I had asked for. Many thanks!
