Material properties

ASTM A532 Class II Type D, with 20% Cr-Mo, is a high chromium white iron designed for enhanced abrasion resistance and high impact applications. This specification is ideal for severe wear conditions, offering excellent wear resistance due to its high chromium content combined with molybdenum which enhances its toughness and hardenability. It's particularly effective in environments where both abrasion and significant mechanical stress are present.

Advantage

1. Excellent wear and abrasion resistance.
2. Enhanced toughness and durability.
3. Resistant to high impact and shock.
4. Suitable for severe wear environments.
5. Good hardenability with heat treatment.

Application

ASTM A532 Class II Type D is extensively used in the mining, milling, and cement industries for critical components such as mill liners, crusher liners, and slurry pump liners. These applications benefit from the alloy's high resistance to wear and abrasion, as well as its ability to withstand high impacts, thus extending the service life of components and reducing maintenance downtime.
