OT: Need tech info on 4130 chromoly steel

OK, so this is pretty darn off topic. But I know some folks around here work with a lot of materials.

I’m looking for the modulus of elasticity of 4130 chromoly steel for a school project. I can’t find it in available textbooks. I’ve looked online and found:

Modulus of Elasticity, 29,725 ksi
( http://gypsy.cad.gatech.edu/courses/me4041/2000/fall/group10/ )

Can anyone confirm this for me? What’s your source? I’d feel more confident about it if it were in a book rather than on the net…

Thanks,
Beth
