EN-GJN-HV600 (XCR23) is extremely abrasion-resistant and suitable for high impact forces. The high chromium content guarantees reasonable corrosion resistance. The applications for this material include wear-resistant pumps.
This extremely hard, abrasion-resistant material stands up well to abrasive contact with grains of sand and coal dust. It is suitable for static parts that are not subjected to knocks. This material is used for grinding/crushing mechanism walls, parts in pulverisation equipment, nozzles, crushing rollers, wear rings, elbows in transportation systems and pump housings (for water and sand).
