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.
AUSTEMPER
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.
