Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. Heat treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming.

P.K. Forge's heat treatments provide the following:
Softening: Softening is done to reduce strength or hardness, remove residual stresses, improve toughnesss, restore ductility, refine grain size or change the electromagnetic properties of the steel.
Hardening: Hardening of steels is done to increase the strength and wear properties.
Material Modification: These processes modify the behavior of the steels in a beneficial manner to maximize service life, e.g., stress relieving, or strength properties, e.g., cryogenic treatment, or some other desirable properties, e.g., spring aging.

P.K. Forge's galvanising process provides outstanding corrosion performance in a wide variety of environments. The galvanising process creates a durable, abrasion-resistant coating of metallic zinc and zinc-iron alloy layers which are bonded metallurgically to the steel and completely covers the item providing a number of significant advantages.

P.K. Forge galvanising provides outstanding toughness, resistance to mechanical damage, slows corrosion to about one sixteenth that of steel and a standard minimum coating thickness is applied even to sharp corners to provide a sound and continuous coating.
