Chromium iron particles can not only be used as deoxidizers in steelmaking, but also as good inoculants and spheroidizers in casting. When used, they can promote the distribution of graphite morphology and improve the quality of graphite cast iron products. Chromium iron particles are cheaper than traditional iron alloy products, so many manufacturers prefer to use chromium iron to achieve product corrosion protection. After using chromium iron particles, newly produced steel Castings will form a hard chromium film protective layer on the surface, which can effectively improve the corrosion and wear resistance of the product. In terms of production costs, the low price of chromium iron particles can achieve cost savings. Long term use of chromium iron particles for smelting can effectively improve manufacturers' profits. Therefore, chromium iron particles are chosen by many manufacturers.
