Brinell vs Rockwell Hardness

Brinell vs Rockwell Hardness
by fkg on 07/08/05 at 11:53:17

I'm trying to compare a Brinell Hardness Number to a Rockwell (RC) Hardness.

A synapses of the problem: I am trying to make sure that a piece of equipment meets a standard specification. The problem is that the standard specification is based on the Brinell Hardness number and the equipment manufactuer has provided his/her hardenss number in Rockwell Hardness (Rc) units.

I've done some research on how the two hardness tests are administered.

And now I am wondering if anyone knows of a way to convert bewtween the two.

You can convert to and from Brinell and Vickers, as both are measured in kgf/mm[sup]2[/sup]

But Rockwell hardness is not proportional to Brinell or Vickers, so you cannot convert between Rockwell and anything else.

Its possible somebody may have created a chart you could look up the numbers from. I do not know of one though.

Thanks Robert!

I did find some charts on this. I think youíre right-I donít think there is a conversion. I think the charts were developed from empirical tests.

There is a little variability in the conversion values (depending on which chart I'm looking at) but fortunately this variance doesnít appear to be significant.
