What Is Ferrochrome

Ferrochromium is an iron alloy composed of chromium and iron. It is an important alloy additive in steelmaking. According to different carbon content, ferrochromium is divided into high carbon ferrochromium (carbon content of 4~8%), medium carbon ferrochromium (carbon content of 0.5~4%), low carbon ferrochromium (carbon content of 0.15~0.50%), Micro-carbon ferrochromium (with carbon content of 0.06%), ultra-fine carbon ferrochromium (with carbon content of less than 0.03%), as well as silicon-chromium alloy, ferro-chromium nitride, etc.

The lower the carbon content of ferrochromium, the more difficult it is to smelt, the power consumption is also large, and the cost is high. Ferrochromium with a carbon content of less than 2% is suitable for smelting stainless steel, acid-resistant steel and other low-carbon chromium steels. Ferrochromium with a carbon content of more than 4% is often used to make ball bearing steel and steel for auto parts. Ferrochromium with a chromium content of about 5% can be used as a chromium addition agent for alloy transfer iron.
