You can grind hardened steel if you're really careful but it's a lot more work and you will go through belts faster. In my opinion, the trade-off isn't worth it. Wait until you can anneal the steel, or set up a temporary heating area with some firebricks (or even your forge body, if you've got it ready) and use a torch to heat the metal.

Phase transformations on grinding of hardened steels. Quenched and tempered steels have a tempered martensite microstructure. The resistance to softening on tempering is increased in alloy steels compared to plain carbon steels . During grinding of steel, the ground surface is exposed to a steep temperature gradient.
HSS is just hardened steel. Usually M2 or M42. Using it to cut a different type of hardened steel usually only gets you a trashed drill bit or endmill. Carbide drills/mills are what you need to machine hardened steel, and even with carbide you need to take it easy. At work, i regularly get jobs to remove broken drill bits or taps from holes.
On the basis of the surface grinding-hardening test, studied on the quality of grinding-hardening in 65Mn steel. The results show that grinding method has insignificant effect on the microstructure and the high hardness value of the completely hardened region at different locations alone the direction of length. The completely hardened region is composed of fine acicular martensites, residual ...

Surface quality of ground parts. Figure 5 compares the mean values of the Ra parameter with the Al 2 O 3 grinding wheel using MQL technique with vegetable oil, synthetic oil, Behran cutting oil 34 and 53 versus MQL flow rate and compressed air pressure. The values were obtained after five stages, each pass of 0.010 mm with work speed of 20 m/min and wheel speed of 30 m/s.
It can be dressed with a sharp diamond. It makes grinding D-2 much easier. Eight inch diameter by one half inch wide was about 500.00 with a 3/32 deep concentration.Rough the work with aluminum oxide wheel then finish with the Noratake. Yep, CBN with lots of coolant is the way to go in hard tool steel above 56 RC.
