Need To Find Mech Properties of 20MnCrB5 steel (EN 10263)

[msjoey]

Hi!

I need some material data to run finite element analysis on a wheel hub. Unfortunately 20MnCrB5 is not common. A lot of google results for 20MnCr5 though, but I'm not sure how close they'd be to 20MnCrB5. The wheel hub has tight tolerances so I'd like to get as accurate results as possible. (Our suppliers are hopeless when it comes to sourcing material datasheets from them)

Because it's for thermal stress + expansion analysis, I'll need the elastic modulus, density, poisson's ratio, yield, and thermal expansion coefficient.

The equivalent grades that I can find for 20MnCrB5 are SCR420B and SAE/AISI 51B20. No hit for ASTM so far.

Thanks in advance!

Here is the YS

The Elastic Mod, density, Poisson's ratio and thermal expansion can be supplied based on values for low alloy carbon steel. You can look these values up yourself.
