4140 Material Properties?

[Shockdesigner331]

Hello all. I've been searching for a comprehensive source for 4140 material properties in all conditions and for various sizes. I have searched through the posts with no luck. I'd appreciate it if anyone can provide me with a website or reference source. Thanks.

4140 is a heat treatable steel,and mechanical properties will vary with section size, quench media and final tempering temperature (draw temperature). That is why you won't find a standard table of mech properties.
