8670 is a substitute for 5160.
C .72% Cr .43% Mn .50% Mo. .07% have no idea what Moly does at that concentration and Nickel .87%
As you can see it isn't much different than 5160, little more carbon and less chromium and manganese, but does have nickel and a tiny bit of molybdenum. I got this from Alpha Knife Supply. They're always nice enough to put comparable steels next to each other.
