company news about Types of ferrochromium

Ferrochrome is an iron alloy with chromium and iron as the main components. It is one of the main alloying agents used in the steel industry. In addition to the main components of chromium and iron, it contains impurities such as carbon, silicon, sulfur and phosphorus. Ferrochrome has high hardness and good wear resistance. Adding chromium to steel can significantly improve the oxidation resistance and corrosion resistance of steel.

Ferrochrome contains 55% to 75% chromium and is classified as high carbon (4% to 10%C), medium carbon (0.5% to 4%C), low carbon (>0.15% to 0.5%C), and low carbon (>10.15% to 0.5%) according to its carbon content. Microcarbon (≤0.15%C) ferrochrome. High carbon ferrochrome is also known as carbon ferrochrome, low, micro carbon ferrochrome is also known as refined ferrochrome. High-carbon ferrochrome produced from chromium ores with low ferrochrome ratio, containing 50% to 55% of chromium, is called furnace grade ferrochrome, and nitrogenous ferrochrome containing N2% to 10% is used as a nitrogen alloying agent. Also known as ferrochrome nitride.
