Heat treat applications are an age-old process that improves strength, hardness, toughness, ductility, and corrosion resistance in metals. At Fisher Barton, heat treating applications is both science and art. It’s here that metallurgy is mastered through the application of worldclass heat treating resources to transform metal into products that last longer and perform better.

Austempering Heat Treatment


Heat treating to provide uniform structure through out material and used to produce MARBAIN®

The Fisher Barton austempering process provides a solution to the expansion problems inherent with conventional quench and temper heat treating. Austempering produces its hardened structure (bainite) gradually and at a relatively high temperature, which provides many advantages. First, bainite’s slow nucleation and growth allows the transformation stresses to dissipate (20-minute bainitic reaction versus instantaneous martensitic reaction). Second, there is an increased plasticity resultant from the relatively high temperatures in the bainite transformation stages. Third, a smaller volume change is associated with the transformation to bainite. Further, bainite is more ductile than untempered martensite.


Annealing is a heat treatment process that changes the properties of a material to increase ductility and reduce hardness by improving ductility and eliminating internal stress.

Brazing (Carbide inserts)

A heat treatment joining process that traditionally uses copper or nickel to adhere to dissimilar metals in which molten filler metal flows into the joint.


Cold Quenching method to increase the toughness and transform austenite to martensite.


A localized heat treatment controlled by heating and cooling of a metal or alloy in order to obtain a set of desired metallurgical properties.

Oil Quench & Temper

Harden surface while retaining core ductility used to carburize. Oil is used to slow the cooling rate reducing the amount of distortion.


Heat treatment in a vacuum environment to provide no oxidation and lower porosity when used in FUSIONbond® process.
