Do you need this material data for FEA or for other reasons. If you need it for FEA then all you really need for analysis is the Poisson's ratio and the Modulus of elasticity.
Those values barely vary due to heattreat condition and chemistry. For modulus you can use 195-210GPa (usually accepted as 30,000ksi) and .29 for poisson's ratio.
A resonable estimate for the UTS of hardened and tempered steel of that HRc is 210-296ksi.
If that wont get you accurate enough results then youl have to talk to some producers of the material. you can try matweb, or maybe carpenter technology.
good luck.
