Austempering

 

Processes

• Austenitizing in endogas from 1450°F to 1650°F
• Quenching in salt from 550°F to 750°F
• In-line rinsing and oiling
• Optional secondary oiling and spinning

Process Capabilities

• Neutral hardening
• Meets AMS 2750 (pyrometry), AMS 2759, CQI-9, etc.
• Continuous belt furnaces
• Plain carbon steels, low alloy steels
• Digital furnace charting (T, t, %CP, s)

Process Features

• Bainitic microstructure that offers good ductility and a wide range of hardness
• Air tempering usually not necessary
• Loading monitor/alarm with safety controls
• Parts come out clean, suitable for plating or coating
• 3-shift operation
