A2 Tool steel fatigue

A2 Tool steel fatigue

A2 Tool steel fatigue

(OP)
I have the Atlas of Fatigue Curves, and Mil-hdbk-5, but I cannot find any data on A2 tool steel SN curves.  I am trying to find the cycles to failure for A2 tool steel hardened to Rockwell 52, and subjected to 100KSI stress.  Estimated UTS is 260ksi, yield-190ksi. Part is 1.5" dia.

1.  Is there a generic material model that I can base the sn curve on.  

2.  Can anyone suggest a good reference for fatigue curves that focuses more on high strength tool steels?  Of particular interest is the effect of heat treatment on endurance properties.

A2-(1.5" dia), similar to ASTM a681, X100crmoV5, generally a medium alloy steel.  

RE: A2 Tool steel fatigue

It is difficult to find fatigue data on tool steels, especially S-N curves.  You are more likely to find low cycle fatigue data (crack growth due to cyclic plasticity).  Perform a key word search of Google SCholar or Scirus (http://www.scirus.net).  The following link has some papers on fatigue of tool steels:
