metal finishings and heat treating

 

 

NEW PLAYER FOR QPQ.

 
  Few Houston shops offer QPQ, a highly demanded process for oil field and other applications. Now G&H can support, offering QPQ and a broad range of metal fabrication, machining and finishing services.  

QPQ / SALT BATH NITRIDING

Liquid Salt-Bath Ferritic Nitrocarburizing with post oxidation commonly known as "QPQ" is a thermo chemical treatment which diffuses both nitrogen and carbon into the surface of steel at a temperature of 1075°F.

This surface hardening process develops a thin, uniform and hard nitride layer which imparts significant surface wear resistance as well as an enhanced fatigue resistance, corrosion resistance, surface lubricity and provides a cosmetically attractive matte black finish with little to no distortion or dimensional change on the material.

G&H Diversified utilizes Delamin Ltd's proprietary non-cyanide chemistries which are environmentally friendly and formulated specifically to meet the requirements of the industry standard specification SAE AMS-2753C.

MATERIALS SUITABLE FOR QPQ

Ferrous metals and alloys that can be enhanced by the nitriding process:

  • Carbon & Low-Alloy Steels
  • Tool & Die Steel
  • Corrosion & Heat Resistant Steels
  • Ductile, Malleable and Gray Cast Iron
  • Ferrous Powder Metal Products

APPLICATIONS THAT CALL FOR QPQ

Salt bath nitriding treatments are used in a broad range of applications, such as: Gears, crankshafts, camshafts, cam followers, valve parts, springs, extrusion screws, die-cast tooling, forging & extrusion dies, hydraulic cylinders, oilfield tooling

ADVANTAGES OF QPQ

  • Surface uniformity
  • Nitride surface layer will not crack or flake
  • Little to no shape distortion or dimensional change
  • Environmentally friendly alternative to hard chrome plating
