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.
What are typical ADI Applications?
Abrasive Protection Liners
Engine Mounting Brackets
Ground Engaging Tools
Hydraulic Pump Bodies
Rack and Pinion Gearing
Railroad Car Wheels
Rollers and Sprockets
Wear Plates and Guides
ADI – Austempered Ductile Iron is a material that offers the combination of high fatigue resistance, wear resistance, toughness, lightness and extensive freedom in designing components together with good machining properties.
Through the iron casting process combined with the heat treatment, the mechanical properties achieved are the typical one of quenched & tempered steel. Austempered ductile iron (ADI) is an excellent opportunity to achieve ambitious goals to lighten and reduce the total production cost of the component.
AUSTEMPERED DUCTILE IRON CASTINGS
Grades 110-70-11, 130-90-09, 150-110-07, 175-125-04, 200-155-02 & 230-185-01
ADI offers the design engineer a remarkable combination of strength, toughness, and wear resistance, with high elongation characteristics. Our ADI can be substituted for steel forgings and castings in many applications, with no loss of performance. The following grades and typical properties are in accordance with ASTM A897.
