WebAug 22, 2024 · D2 really should be re-annealed after a botched heat treatment. Maybe Larrin or someone can give exact procedure on doing that, but it requires a hold at “x” temp for “y” time, and then drop down to “z” temp at a rate not to exceed “xy” degrees per hour. Then there is the more simple “bladesmith anneal”. http://cintool.com/documents/High_Carbon/D2.pdf 883 tank cover WebO1 Tool Steel.
