Technical FAQ: High Chrome White Iron & ASTM A532 Liners

What is the hardness of WALKSON White Iron Liners?

Our liners typically achieve a hardness between 500 to 700 BHN (roughly 50 to 65 HRC). This is achieved through precise alloying with chromium and molybdenum, followed by a controlled cooling or heat treatment process to ensure a martensitic matrix with secondary carbides.

Can white iron liners handle high-impact conditions?

While white iron is exceptionally hard, it is inherently brittle. For high-impact applications, we recommend our Bimetallic Liners or Composite Liners, which combine a white iron wear surface with a ductile steel backing to prevent fracturing under heavy shock loads.

Which industries benefit most from High Chrome White Iron?

Industries dealing with extreme abrasion, such as Mining (crusher liners), Power Generation (coal pulverizer parts), and Cement (chute liners), find white iron to be the most cost-effective solution for extending equipment uptime.
