Material properties

ASTM A532 Class II Type B, also known as 15% Cr-Mo or High Chromium Molybdenum Iron, is renowned for its exceptional durability and resistance to wear and impact. This high-chromium white iron is enhanced with molybdenum to increase its toughness and hardness, making it ideal for heavy-duty applications that require resistance to severe abrasion and impact. The alloy's capability to withstand harsh environments makes it a preferred choice for components like mill liners and crusher liners in the mining and cement industries.

Advantage

1. Superior abrasion and wear resistance.
2. Enhanced toughness with molybdenum addition.
3. High resistance to impact and shock.
4. Suitable for high-stress applications.
5. Capable of heavy-duty performance.

Application

15% Cr-Mo is primarily used in the mining and cement industries, where components are exposed to severe wear and tear. It is commonly employed for parts such as mill liners, crusher liners, and slurry pump liners. These applications benefit significantly from the alloy's high hardness and resistance to impact, which substantially extends the service life of wear parts and reduces downtime and maintenance costs.
