This process develops a tough, high-carbon, bainitic case on high performance components.
Carbo-Austempered parts have remarkable impact properties that are superior to either neutral hardened or carburized steels. Carbo-Austempering is routinely applied to steel gears, shafts, and power transmission parts that undergo periodic overloading in service.
The Carbo-Austempering™ process is a high performance steel heat treatment that combines a high carbon bainitic case with either a bainitic or tempered martensitic core to produce a component with an exceptional combination of strength and toughness.
Carbo-Austempered ™ steel exhibits:
- Higher tensile strength
- Increased wear resistance
- Greatly improved impact properties
- Increased elongation
- Lower distortion
- No cracking during quenching
- Increased fatigue strength (in high load, low cycle fatigue application)
Typical applications of Carbo-Austempered™ Steel include:
- Transmission shafts
- Output Shafts
- Pump Shafts
- Differential Pinions
- Spline Drives
- Parking Pawls.
