Posts classified under: Austempered Ductile Iron

Austempered Ductile Iron (ADI) is a specialty heat treated material that takes advantage of the near-net shape technology and low cost manufacturability of ductile iron castings to make a high strength, low cost, excellent abrasion-resistant material. Six grades of ADI are available to address property combinations of high strength, abrasion resistance and toughness for converting from costly forgings, weldments and assemblies.

Austempered Ductile Iron (ADI) had its commercial genesis in 1972. Growth of ADI since then has been impressive with worldwide production in 2010 estimated at over 500,000 tons. Ongoing development of ADI has hinged on improving ductile iron technologies, increased knowledge of the Austempering process as applied to cast irons, and the deployment of technically improved, higher productivity, greener heat treating systems and technologies.
