VACUUM HEAT-TREATING SYSTEMS
The HVF and VVF systems from Nitrex deliver superior performance for austempering applications requiring high strength and toughness.
Austempering is a heat treatment that produces a ductile, stable bainitic structure in steel applications. The treatment is done in two steps: first heat into the austenite phase and then quench to a temperature level so that the austenite is transformed into bainite instead of martensite. Bainite is tougher than martensite.
BENEFITS
The HVF and VVF systems from Nitrex deliver superior performance for austempering applications requiring high strength and toughness.
Austempering is used in a wide variety of applications in the automotive, rail, and heavy-engineering industries: applications include gears, shafts, crankshafts, camshafts, clutch plates, seat belt components, drive shafts, rollers, rocker arms, and many others.
Austempering benefits ferrous metals, particularly ductile irons and medium- to high-carbon steels including:
