The Duracast® DC17 castings are produced by Bradken’s in-house foundries. An automated moulding machine allows for high volume, low-cost manufacturing. Custom shapes can be cast to solve complex wear problems and to allow for attachment methods such as fish-tail liner bolts. A heat treatment process is used to maximise its wear resistance.
Duracast DC17 is a enhanced white iron alloy based on ISO21988/JN/HBW555Cr16. The major alloying elements, Chromium, Carbon and Molybdenum, give this material its superior abrasion resistant properties.
A typical chemical composition is provided below:
The microstructure of Duracast DC17 is crucial in providing superior wear performance. The heat treatment cycle transforms the softer as-cast microstructure into hard, wear-resistant material. This microstructure consists of a network of interconnected eutectic M7C3 carbides in a martensitic matrix.
