We have advanced inspection equipments: chemical composition detection spectrometer, metallographic microscope, hardness detector, impact value detector, drop test bench, metal defect detector (detecting internal damage of raw materials), wire cutting machine, excavator, etc. The equipment ensures that the raw materials from the factory to the finished products are qualified products. According to different materials, all our products are heated and quenched at high temperature for 2-3 times. It completely eliminates the internal stress of the product, does not crack, and has high core hardness. The transparent layer is thicker to achieve more wear-resistant effect. The as cast defects caused by metal in the smelting process are eliminated through direct casting, and the microstructure is optimized. At the same time, because the perfect metal streamline is retained, the mechanical properties of forgings are usually better than those of castings of the same material. Forged steel ball must be the most wear-resistant material to ensure wear resistance. In addition, some companies have independently developed high-efficiency wear-resistant alloy steel materials.
