Austempered Ductile Iron Casting
An Austempered Ductile Iron Casting is a high strength, wear resistant, heat treated
Ductile Iron which exhibits twice the strength of conventional Ductile Iron for
a similar level of difficulty. ADI can replace most steel forgings at a reduced
cost.
Typical Applications for Austempered Ductile Iron Casting:
Steering Knuckles, Snow Plow Shoes, Spring Hangers, Wear Plates, Plow Points and
Shears, Gears, Guides and Rollers, Digger Teeth
Advantages of Austempered Ductile Iron Casting:
Higher Tensile and Yield Strength, Lower Weight then Steel Forgings. Excellent Wear
Resistance. Excellent Impact Strength
