Quench the parts from 870C in oil. Temper at 160C for 2h.

adyonel's answer is for an atmosphere protected furnace with direct oil quench.
With your vacuum equipment you should be able to perform a few systematic tests. It is worth trying.

No Goahead, my answer is for vacuum furnace too. 8,5 bars is not a very low pressure.
