Today I have to get a couple blades done. Both are almost identical 4" utility/hunters. One in 52100 and the other is W2. Both came from Aldo, bar stock, spheroidized, stock removal only. My heat treat for both steels is pretty much the same. Is that OK, or am I missing something? My thought is most of the lower alloy tool steels can be treated almost identical.
In the past, I have done normalizing before grinding, and then done a spher anneal, grind, then stress relieve, then harden. This go around is going to be more simple. They are ground now and will be normalized, cycled, and hardened.
Both will get 1650F for a few minutes
Both will get the step down procedure, 1550F, 1425F
Right to hardening...both getting a good soak at 1475F
The W2 will get P50, the 52100 130F canola
Both get initial 375F tempers and walked up if needed, probably needed up to 400F.
Does this procedure look good for both steels? Thanks for the input!
