Ferro chromium is an iron alloy composed of chromium and iron. It is an important alloy additive for steelmaking.
According to different carbon content, ferro chrome can be divided into high-carbon ferrochrome (10% C content), low-carbon ferrochrome (0.25% C content), Micro-carbon ferrochrome (0.03%-0.15% C content).
The lower the carbon content of ferrochrome, the more difficult it is to smelt, the higher the power consumption, and the higher the cost. Ferrochrome with a carbon content of less than 2% is suitable for smelting stainless steel, acid-resistant steel and other low-carbon chromium steels. Ferrochrome with a carbon content of more than 4% is commonly used to make ball bearing steel and steel for auto parts.
