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 percent to 0.5 percent C), and micro carbon ( Less than or equal to 0.15 percent 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 kind of high carbon ferrochromium produced from chrome ore with low ratio of chromium to iron. The ferrochromium containing 50 percent ~55 percent Cr is called furnace charge grade ferrochromium, and the ferrochromium containing nitrogen containing N2 percent ~10 percent is used as nitrogen alloying agent, also called nitrided ferrochromium.
