You can figure out how much the strength variation could be by google
searching for "Correlation hardness ultimate strength rockwell c"
meaning that you are looking for the correlation between ultimate
tensile strength and the hardness as measured on the Rockwell "C" scale.
You will be able to see that there is an enormous strength difference
between Rockwell C47 hardness and C58 hardness.
AFAIK there is a correlation between hardness and ultimate tensile
strenght for steels with a certain plastic deformability. For hardened
steels, it is difficult to measure tensile strength, because fracture is
flaw-controlled here. Just curious: Did you ever carry out a tensile
test using a C58-hardness-specimen?
Unfortunately, I don't have the standards in my actual office, but I
rememeber that the correlation between hardness an UTS is valid only up
to a certain maximum hardness.
