COMPANY ENVIOMENT

PRODUCTS INTRODUCTION

Our company mainly produces Ф20mm—Ф130mm 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, building materials, 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.

High Chrome casting steel ball

High chrome casting grinding ball, chrome concentration is 10%－24%, hardness ≥HRC58. High chrome casting grinding ball is one of the wearable steel ball with better performance-price-ratio, and its extensive usage has won itself a high share in the market.
