Our company mainly produces 8 mm-1 50mm low, middle, high chrome alloy casting iron ball. Huafu chose large angle steel, scrap steel and other raw material, according to different product, needs adding chrome, manganese, vanadium, titanium, rare earth and as so on metal. Products high hardness, low wear, good toughness and less broken, in the process of using sphere will further improve the surface hardness, wear resistance.
Chrome alloy casting iron ball are widely used in cement, buildingmaterials, metal mining, coal slurry thermal power, chemical engineering, ceramic coating, light industry, papermaking, ultrafine powder preparation of magnetic materials and other industries and further processing.
