Chromium White Iron Has Better Wear Resistance than Other Alloys
Chrome-white-iron has its unique microstructure. It can offer superior abrasion resistance over other alloys, including steel.
ASTM A532 also confers specific recycling, reusing and repairing advantages, which results in a lower environmental impact and significant cost savings.
Some foundries offer the option to recycle chrome white iron castings and parts. Once removed from service, the casting can be melted down, combined with other raw materials and transformed into new, wear/abrasion resistant products. The benefit of this process is obvious – less landfill waste and environmental effect, such as high chrome white iron liner, it can be removed, recycled and a new liner installed. The new liner is refurbished and retested, and downtime is kept to a minimum as the foundry supplies a spare unit. Productivity is maintained and cost savings is realized.
ASTM A532 possesses superior wear/abrasion resistance. By replacing steel with chrome white iron you can significantly extend the wear life of a casting or product. This reduces the total amount of material used over the life of a project, saving downtime and money.
Some products, such as certain pipe products, are meant to be rotated. By reusing products in this fashion, the initial investment is extended over multiple uses. It is possible to successfully repair many chrome white iron products such as an elbow, lateral, etc.
