Custom high chrome white iron castings with 12–28% chromium content for maximum abrasion and corrosion resistance. Applications include pump casings, impellers, pipe elbows, cyclone liners, classifier liners, screen panels and any component requiring extreme wear resistance in abrasive and corrosive service. Hardness achievable up to 67 HRC.
High chrome white iron castings are specified wherever severe abrasion and corrosion combine to destroy ordinary steel components. The chromium carbide microstructure provides exceptional resistance to low-stress scratching abrasion and corrosive wear.
Pump casings, impellers, suction liners (throatbushes), side liners and shaft sleeves for centrifugal slurry pumps in mineral processing, tailings handling and coal preparation. High chrome iron dramatically outperforms standard rubber-lined pumps in high-temperature or chemically aggressive slurry service.
Feed chamber liners, cylindrical section liners, apex sections (spigots) and vortex finders for hydrocyclones in classification, desliming and thickening circuits. High chrome iron provides 3-5x the wear life of polyurethane liners in coarse, high-density slurry applications.
Cast high chrome iron pipe elbows, 45° and 90° bends, tee sections and straight pipe for abrasive slurry transfer lines. Manufactured with standard flange connections (ANSI, DIN, AS) or custom spigot/socket ends to suit existing piping systems.
Spiral classifier scroll liners and tank wear plates, rake classifier tine liners and screw conveyor flight liners for classification of fine mineral slurries. Wear-resistant liners for mechanical classifiers handling highly abrasive fine ground ore pulp.
Impact-resistant liner plates for transfer chutes, loading boxes, feed hoppers and discharge chutes. Available as flat liner tiles, radius sections and formed liners. High chrome iron provides superior life to AR steel plate in fine, high-velocity abrasive material flow applications.
We manufacture any high chrome iron casting to your drawing or sample. From small pump impellers to large classifier feed boxes — supply dimensions and application data and we recommend the optimum chrome content and heat treatment specification.
