Re: Barrel Nitriding Questions
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: m_gale</div><div class="ubbcode-body">Nitriding is a waste of time and money unless it is done by the company who manufactured the barrel. It can dramatically alter the hardness/temper of the steel unless it can be done at a temperature less than what the barrel was subjected to when it was heat treated. </div></div> which is a physical impossibility.
here I found the steps of the process listed on Burlington engineering's website:
The system has many stages, from the pre-treatment-cleaning, to pre-heat furnace, to the Melonite salts, quench salts and water rinses.
basically after all the pre stuff its then processed in high temperature salts (1000-1200).
afterwards its quenched in a lower temperature salt (around 300-500 degrees)to establish hardness.
