Regarding heat treating O1 tool steel, i have a question regarding the process that i am hoping someone can help me with.
i can get to a bright orange…should i be getting to bright red?
at bright orange, i test on a magnet and it “sort of” feels non-magnetic…
after re-heating to bright orange after testing, i quench/swirl in oil
at this point, when i re-test on magnet, it feels magnetic…should the non-magnetic nature remain?
i also test with s steel file, and it “sort of” sounds “glassy”
i tried hardening 3 times as above…the first two times, the tool was definitely still magnetic at bright orange…
the third time, i was also seeing bright pinpoints of color within the tool…is this significant?
the tool i was trying to harden was a quality stamp from Infinity Stamps…i wanted to anneal and taper tip for better visibility, and then re-harden and temper…
i am not sure if i hardened correctly…
any help would be greatly appreciated.
