Chrome White Iron Liners

Posted by Penticton Foundry on October 14, 2015

Chrome white iron liners, with their combination of martensite and carbides, offer superior abrasion and wear resistance. They can be found in the mining, potash, concrete, cement, recycling and the pump industries. Chrome white iron liners can also be combined with a steel pressure boundary for the hydrotransport of severe slurry in the Oil Sands.

We use a proprietary process to create our high chrome white iron products. Interestingly, there are a number of myths and facts about chrome white iron, the least of which is that it cannot be machined. Other myths include that it is too brittle for applications involving impact or that it won’t outperform materials of a similar hardness. None of this is true. Indeed, chrome white iron will often outperform other wear options, including AR plate and chromium carbide overlay.

Why Use Chrome White Iron?

Superior wear resistance - particularly against gouging and abrasion
Corrosion resistance is much higher than other options like AR Plate
Chrome white iron liners are recyclable
Cost savings – fewer shutdowns due to extended service life
Liners can be made thicker in high wear areas
