Ferrochromium alloy for casting
Ferrochromium is an iron alloy composed of chromium and iron. It is an important alloy additive for steelmaking. Ferrochromium is divided into high carbon ferrochrome (carbon content 4~8%), medium carbon ferrochrome (carbon content 0.5~4%), low carbon ferrochrome (carbon content 0.15~0.50%) according to different carbon content. Micro-carbon ferrochromium (carbon content is 0.06%), ultra-micro carbon ferrochromium (carbon content is less than 0.03%), silicon-chromium alloy, nitride ferrochromium, etc.
The lower the carbon content of ferrochromium, the more difficult it is to smelt, consume more electricity, and increase the cost. 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 commonly used to make ball bearing steel and steel for automobile parts. Ferrochromium containing about 5% chromium can be used as a chromium additive for alloy transfer iron.
