RA in Ovako 146s
RA in Ovako 146s
(OP)
Hi All,
I have attached a micrograph of Ovako 146s case hardened steel, I am estimating around 10% RA in the case (independent lab from H/T company state "No RA") I am also achieving hardness results to support the level of RA agains independent lab results of >800Hv! Is there a more accurate way of determining without the use of XRD etc?
Thanks

The above link is of the samples from the HT comapany and from an independent lab (supposedly from the same sacrificial test piece). Microstructures look very different and a difference in hardness of approx 200Hv.
