Heat treating to meet a specific hardness range
Heat treating to meet a specific hardness range
(OP)
I'm looking for some feedback on heat treating material to meet a given micro hardness range.
Am I okay to heat treat the same piece of material as many times as needed to get within a targeted hardness range or does the reintroduction to heat change the material in a way that would impact other performance propterties besides hardness. for example if I am testing each time to still be sure my Tensile and elongation still pass for a given Temper So at the end of the day I have a piece of material that passes both hardness, Tensile and Elongation but it has been heat treated 3 times instead of once.
Thank in advance for all the feedback.

Arunmrao - along the lines of your response. When I test for tensile, elongation, and hardness for a specified temper all test are passing, but I have heat treated it 3 or more times. My concern; is there a degradation in the alloy that may not be reflected in the listed test results after seeing heat (3 or more times) i.e. grain size, scaling that may not be visible upon inspection using the naked eye.

Sorry ,I have no clue about the material. I am sure the heat treatment will be done under vacuum . Issue like scaling, is not possible ,It is better, I do not stick out my neck any more .
