Low carbon ferrochrome (LC FeCr) is a ferroalloy additive used in the production of stainless steel, acid-resistant steel, and heat-resistant steel. It can also be used to make chrome metal and ferrochrome. LC FeCr is made from raw materials like silicon-chromium alloys, chromite, lime, and other metallurgical materials.
