Salt Bath Black Nitride-SBN-QPQ

Salt bath black nitrocarburizing/QPQ coatings improve the formative and functional properties of ferrous alloys. This type of coating produces a thin, uniform, hard nitride layer that results in little to no dimensional distortion or change to the material.

Benefits of QPQ coatings include:

  • Significantly increased surface hardness
  • Improved surface wear and fatigue resistance
  • Enhanced surface lubricity
  • Increased corrosion protection
  • Sleek, black finish

Popular in firearm applications, GH Metal Finishing utilizes HEF USA’s proprietary Melonite® chemistries. Classified as non-toxic, Melonite® meets SAE AMS-2753C standard specifications.
