Austempered Materials and their Applications to Drive Line and Suspension Components
The Austempering process is a high performance heat treatment that, when applied to ferrous materials, produces components that, in many cases, have properties superior to those processed by conventional means. The Austempering processes include: Austempered Ductile Iron Austempered Gray Iron Austempered Steels and Powdered Metals Carbo-Austempered™ Steels Austempered Ductile Iron (ADI) has an exceptionally high strength-to-weight ratio with good fatigue strength and fracture toughness. In fact, with strength three times greater than that of aluminum with only two and a half times the density, ADI can replace aluminum at equal weight for a substantial cost savings. Austempered Gray Iron (AGI) has an excellent combination of noise damping, wear resistance and thermal conductivity. It has received a great deal of attention as diesel engine manufacturers increase cylinder pressures to meet ever more stringent exhaust requirements.
