Austempered Ductile Iron (ADI) is a type of ductile iron that is characterised by increased toughness, tensile strength and wear resistance compared to normal ductile irons. These properties are achieved by heat treatment of an alloyed ductile iron using an austempering process. The mechanical properties of ductile iron and ADI are primarily determined by the metal matrix.

It’s a console frame developed in 900/650/9 grade for John Deere, Canada. We have only developed the casting with Heat treatment our business partner in this project will be machining and assembling the part and send it to John Deere, Canada.

It is a Bar Pivot used in a sway bar assembly of Hitch system used in RV’s. We developed it in 1100/7 grade but later customer changed it to 900/9 grade (which means 900 Mpa Tensile Strength and 9% elongation). This is a bulk product where the aesthetic finish of the part is really important, and we supply as per customer requirements. It is supplied in fully finished condition.

Applications of ADI parts

Heavy Truck and Bus Components

Economic growth drives the need to haul heavier loads over longer distances, resulting in more time between vehicle maintenance and some difficult engineering challenges. The Heavy Truck industry recognised the potential benefits of Austempering solutions many years ago. Manufacturers took advantage of the versatility of Austempered Ductile Iron (ADI) to introduce innovative light weight, high performance parts. Diesel Engine Timing Gears, Hypoid Ring and Pinion Gears, Jack Stand Gears, Wheel Hubs, Suspension Brackets these are some components which are manufactured by using austempering ductile iron.

Railway

The Railway industry is constantly looking to improve its products and the safety and efficiency of rail transport. The railroad industry uses ADI for suspension housings, top caps and friction wedges, track plates, repair vehicle wheels, nipper hooks, and car wheels. Construction Equipment Heavy duty and hard working, construction equipment can benefit greatly from the use of tough, wear resistant Austempered Irons and Steels. Whether for ground engaging components such as bucket teeth or engine and powertrain parts, Austempered Ductile Iron (ADI) and other Austempered materials can improve the performance of your equipment.

Light Vehicle

The automotive industry is constantly looking to increase performance, and reduce the cost and weight of the vehicles they produce. Austempered materials have a proven track record of providing strength and dependability for safety components, suspension systems, and drivetrain applications. Miscellaneous Industrial Miscellaneous industrial applications include brackets, lever arms, knuckles, shafts, cams, sway bars, sleeves, clevises, conveyor components, jack components, bushings, rollers, molding line components, fixtures, gears, sprockets, deck plates, and all sorts of power transmission and structural components. Agricultural Farming and agricultural applications for Austempered Ductile Iron (ADI) include plow points, till points, trash cutters, seed boots, ammonia knives, gears, sprockets, knotter gears, ripper points, tractor wheel hubs, rasp bars, disk parts, bell cranks, lifting arms, and a great variety of parts for planters, plows, sprayers and harvesters.

Sporting Goods

Even the sports goods industry has adopted Austempered Ductile Iron (ADI) for its high strength to weight and superior wear resistance. Bobsleigh runners, Sword blades, Gun components are manufacturing by using austempered ductile iron.

Defense

The defense industry has been relatively slow to adopt Austempered Ductile Iron (ADI), however some of the applications include track links, armor, ordnance and various hardware for trucks and armored vehicles.

Gears/Shafts/Powertrain

For high performance gear and power train manufacturers, Austempered materials offer greater wear resistance, reduced noise, improved bending and contact fatigue, as well as increased strength and durability. Diesel Engine Timing Gears, Hypoid Ring and Pinion Gears, Off-Highway Drive Axles, Ring Gears, Gear Housings, Sprockets, CV Joints, Differential Housings, Wheel Hubs etc are prepared by using austempered ductile iron.
