What is Austempered Ductile Iron (ADI)?

Austempered ductile iron castings, or more commonly ADI castings, is a ductile iron casting which is processed by a special heat treatment. The austempering process, with ductile iron’s superior castability, results in a material which can be used to cast complex shapes, with a greater consistency of quality, and often at less cost.  The heat treatment requires an interrupted quench, usually into a salt bath, to cool the cast part at a planned rate and long enough to achieve the desired austempered result. The resulting material has a combination of exceptional strength and toughness, meeting and often exceeding those of alloy steels.


What are some Benefits of Austempered Ductile Iron Castings?

• Up to 40% less cost than hardened steel forgings.

• Lower operating noise levels.

• 10% less weight than steel.

• Better wear than case hardened steel.

• Excellent resistance to crack propagation.

• Good impact strength to -120ºF.

• Work hardening.
