Advantages of High Chromium White Iron Casting

Extreme Wear Resistance​

Compared with steel, super-hard materials have a service life that is 2 to 5 times longer, thereby significantly reducing replacement costs in abrasive environments

Cost-Effective Durability​

Extended service life can reduce downtime and replacement costs by 30–50% compared to alloy steel or ceramic materials. It can be cast into complex shapes (such as pipe linings and exhaust valves) with minimal processing, thereby reducing production costs.

Zero Cracking & Longevity

Advanced alloy formula ensures crack-free welds, extending equipment lifespan by 2-3X.

Adaptability to Harsh Environments

High temperature resistance (≤750°C) and corrosion resistance, with stable performance in applications such as sintering machine grate plates and slurry pump flow parts.

FAQ

Is this hopper suitable for handling materials other than coal?

While this hopper is specifically designed for coal handling applications due to its exceptional wear resistance, it can also be utilized for other abrasive materials with similar characteristics.
Our product has no limit to quantity, it can be ordered according to customer requirement.
M₇C₃ carbide has a hardness of HV 1200-1800, and its service life can be increased by more than three times in severe abrasive wear conditions.
It’s commonly used in mining, cement plants, power generation, and wastewater treatment—anywhere parts face heavy wear, abrasion, or corrosion.

What Our Clients Are Saying

Mark Rodriguez
Mark Rodriguez

We use high chromium white iron liners in our rock crushers, and they’ve cut our maintenance costs in half. These parts last twiceas long as the steel we used before—no more frequent replacements!

Carlos Gomez
Carlos Gomez

Yes, their initial cost is twice that of other products. But our mud pump housings last eight months longer than other products! Every penny is well spent to achieve zero downtime.
