Definition Of Ferrochrome

An iron alloy mainly composed of chromium and iron. It is one of the main alloying agents used in the steel industry. In addition to the main components chromium and iron, it also contains impurities such as carbon, silicon, sulfur, and phosphorus. Chromium iron contains 55% to 75% chromium, and is divided into high carbon (4% to 10% C), medium carbon (0.5% to 4% C), low carbon (>0.15% to 0.5% C), and micro carbon (≤ 0.15% C) chromium iron according to its carbon content. High carbon ferrochrome, also known as carbon ferrochrome, and medium, low, and micro carbon ferrochrome, also known as refined ferrochrome. A type of high carbon chromium iron produced from chromium ore with a low chromium to iron ratio, which contains 50% to 55% Cr and is called furnace grade chromium iron. Additionally, nitrogen containing chromium iron with N2% to 10% is used as a nitrogen alloying agent, also known as nitrided chromium iron.
