![]() This tough work-hardening material has proved to be an excellent replacement for hardened steels. Applications like for gears ADI has been used with great success. ![]() What Can Austempered Ductile Iron Castings (ADI) be Used for? – Application DataĪustempered ductile iron (ADI) is often used where high strength is needed and where excellent wear resistance and fatigue strength are required. Up to 40% less cost than hardened steel forgings.Įxcellent resistance to crack propagation. ![]() What are some Benefits of Austempered Ductile Iron Castings? The resulting material has a combination of exceptional strength and toughness, meeting and often exceeding those of alloy steels. 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 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 austempered ductile iron casting products are widely used for auto-car components, trailer suspension system, truck parts, crankshafts, railcar wheels, cylinder lock cases, tow hooks, cylinder liner, agricultural machinery components, etc.Īustempered ductile iron castings, or more commonly ADI castings, is a ductile iron casting which is processed by a special heat treatment. ![]() Heat treatment process: isothermal quenching process ADI casting parts austempered ductile iron process castings foundry China ![]()
