>Generally to anneal, you want to close to the metals austenising temp (usually somewhere between 750-850C for most steels) and then hold it at those temps for a while- then let it cool very slowly in something like vermiculite or dry sand
This is called the laminar anneal. It creates coarse pearlite which is bad for knife steels with higher carbon than the eutectoid amount (which is many knives). For these, a spheroidal anneal would be preferred. As you say, kinda hard to give specifics without the type of steel, or what state it is in before annealing.
