Rockwell C & UTS
Rockwell C & UTS
(OP)
Hi all,
I've undertaken a Rockwell C hardness test on a camshaft lobe & follower and both have returned a reading of 33 RC.
I've found a table which converts this to a UTS of 1048 MPa.
Now, I can only assume this relates to some sort of steel??
Thanks for any help

RE: Rockwell C & UTS
This is only an approximate conversion to ultimate tensile strength and is applicable to steel, in general (carbon and low alloy). To identify the steel requires different testing methods.
RE: Rockwell C & UTS
the formula doesn't take into account which steel it is, just simply 'steel'. Can I safely assume the material is indeed steel?!

Many cams are case hardened and with RC you may be punching through the surface.
Though RC33 does sound rather low for a cam lobe.
