Rule of Thumb for Determining Max Hardness of Steel?
Rule of Thumb for Determining Max Hardness of Steel?
(OP)
Is there a simple technique for determining the maximum hardness that steel can be processed to? If I have 1022 steel, how can I determine the max hardness value from carburizing or nitriding etc? Also, is there a way to create a localized alloy in a plain carbon steel through processing? In other words, if I have a thin rod (0.20" diameter) of 1022 steel and I want to make the left half of the rod similar to A-2 tool steel, is there a way to create a localized alloy in this area through processing? (Probably a dumb question but I thought I'd ask...). Also if I have a carburized tip of 1022 that will reach high service temperatures due to friction with steel, will this cause localized tempering in the hardened tip that will lower the hardness value? I'm assuming this isn't a problem with, say A-2 tool steel, but why?

The alloy elements in A2 tool steel (roughly 5% Cr, 1% Mo, .4% V) allow the steel to maintain its hardness during tempering and exposure to elevated temperatures. These elements also give the material it's air-hardening characteristics.
