Ferrochrome

Ferrochrome is a ferroalloy composed of chromium and iron. According to the carbon content, it is divided into high-carbon ferrochrome (C ≤ 10% 4-8), medium carbon ferrochrome (C ≤ 4.0% 0.5-4), low-carbon ferrochrome (C ≤ 0.5% 0.15-0.5) and micro carbon ferrochrome (C ≤ 0.15% 0.06).

Commonly used are silicon chromium alloy, chromium iron nitride, etc.

It is mainly used as alloy additive for steelmaking and added in the later stage of steelmaking and refining. Low and micro carbon ferrochrome must be used for smelting low-carbon steel such as stainless steel.
