BLACK NITRIDE:
Black Nitride is a process commonly referred to as SBN (Salt bath nitride) and QPQ (quench polish quench). These are a form of nitrocarburizing or a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change which causes the hardening of steel. The chemical bath results in a deep dark black with a harder, more durable finish.
