ACTech - Austempered Ductile Iron

Austempered ductile iron, also known as ADI, has an austempered matrix with embedded spheroidal graphite. The matrix and thus also the properties are set by isothermal heat treatment (cooling from the austenitization temperature) to the transformation temperature in accordance with the grade. As a result, the material scores with properties that are similar to those of rolled and forged steels, or even exceed these in some cases – and at significantly lower weights. Material standard: DIN EN 1564.
