Newbie to the forum, so forgive me if I post this in the wrong place!
If I heat steel (a bearing outer race to be exact) from room temperature to approx 200C, the hardness of the steel will reduce. If the temperature is then allowed to reduce back to room temperature, what will happen to the hardness? Will it rise to what it was previously, or will it stay at its lower value? Thanks
