Austenitic Matrix of Acicular Ferrite known as Ausferrite which
makes up the microstructure of ADI.
Austempered Ductile Iron [ADI] provides a range of high strength
irons with higher ductility and toughness. Through the work
hardening characteristics of the matrix these irons have an
exceptional blend of wear properties and toughness. These irons have
the advantage that the base iron is readily machinable before heat
treatment allowing hard wearing close tolerance and mating parts to
Tensile：Twice the tensile strength of Ductile Iron, work Hardens.
Wear：Wear resistance superior to Steel at any hardness level, and
ideal for high abrasion applications.
Weight：10% lighter than Steel.
Cost：Energy savings over Steel, easier to machine than Steel reduced
Near net shaped castings means even less machining.
Applications & Examples
The properties of ADI coupled with the cost and flexibility benefits
of ductile iron castings means the potential for ADI applications is
Agriculture - excelent resistance to soil wear.
Digger/Grab Teeth - high strength and wear resistance.
Industrial - wear components, pumps, etc.
Gears - Gears for wear resistance and better vibration damping than
Construction - crushing, grading and wear components etc.
Food & Feed milling : grinding, mixing, palletizing etc.
