Definitions

Open-fire Normalize: Forgings are heated to about 100 F over the upper critical temperature followed by air cooling to room temperature.
Benefit: Raw forgings have asymmetrical properties based on the direction of material flow which makes machining difficult. Normalize process homogenizes the microstructure and reduces the hardness. They both make the parts conducive to machining.

Atmosphere Normalize: Parts will be normalized in protective atmosphere to minimize scale (iron oxide) and decarburization.
Benefit: With protective atmosphere, the amount of scale on the parts will be minimal. Helps in reducing steel requirement for the forgings and eliminating shot blast process.

Isothermal Anneal: Heat up is similar to normalize in the first furnace, but the parts will be held at a specific temperature instead of air cooling until the transformation is complete in a second furnace.
Benefit: Normalize process may not be able to produce machinable microstructure in certain grades and high alloy steel. Isothermal anneal is required in those situations.

Spheroidize Anneal: Low temperature process to produce spheroidized carbides.
Benefit: Required microstructure for cold forming processes. Also preferred for machining of high alloy steel grades by reducing hardness.

Quench & Temper: Austenitize to about 50 F over the upper critical temperature followed by quenching in Oil, Polymer, or Water, then temper below the lower critical temperature to produce desired hardness.
Benefit: Capable of producing a wide range of hardness by varying the tempering temperature.  Microstructure produced by quenching is resistant to wear.

Atmosphere Quench & Temper: Parts will be austenitized in protective atmosphere to minimize scale (iron oxide) and decarburization.  Tempering occurs at low enough temperatures that scale and decarburization are not produced.
Benefit: With protective atmosphere, the amount of scale on the parts will be minimal. Helps in reducing steel requirement for the forgings and eliminating shot blast process.

Ferritic Nitrocarburizing: Ferritic nitrocarburizing is a case hardening process in which nitrogen and carbon are diffused into ferrous metals at sub-critical temperatures.
Benefits: A green alternative to chrome plating, the parts have high wear resistant and superior corrosion resistant surface with increased service life.

Subcritical Annealing: Forgings or castings are heated to just below the lower critical temperature followed by air cooling to room temperature.
Benefit: Reduces machining costs by eliminating residual stresses in the parts from forming or casting operations.

Coating (Phosphate and Lubrication): Coating chemically reactive zinc phosphate on the steel parts’ surface followed by coating with lubrication. Different types are lubrication will be used based on the cold forming requirement.
Benefit: Near net shape parts can be produced which will result in reduced raw material requirement and saving in machining. Heating the parts is  not required to form parts which also aids in cost saving.

Pickle and Oil: Initially, the oil and grease from the material surface will be removed using caustic cleaner. Material will then be pickle cleaned in an acid bath for removal of surface oxides. Finally, the parts will be dipped in oil to protect them from rusting.
Benefit: Metallic and nonmetallic contaminations will be removed from the surface of the material. Material can be stored for a while without the risk of rusting.

Phosphate and Oil: Zinc phosphate coated material will be dipped in oil.
Benefit: Oil coated parts will remain rust free for a long time.

Shot blast clean: Removal of scale from any of the heat treat processes by impinging the parts’ surface with hard steel shots.
Benefit: Scale on parts must be removed for proper machining and increased tool life.

Shearing: Cutting bar stock to specific weights using shear knives.
Benefit: Shearing is the first step in converting bars into forgings by producing billets. Quicker and less expensive compared to sawing.

Sawing: Cutting bar stock to specific weights or lengths with high speed carbide blades.
Benefit: Needed for steel grades that are prone to cracks in both shearing and further forging operations.

Stress Relieve: Parts are taken to and held at an appropriate temperature to relieve the residual stresses created in the prior operations.
Benefit: Operations such as rough machining and cold forming can generate residual stresses in parts. If not removed, these stresses can release themselves in an uncontrolled fashion causing dimensional issues at subsequent operations. This process is required on welded material to keep them stress-free.
