Black Ferro Chrome, For Constructional, Industrial

Ferrochrome is ferroalloy 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 also contains impurities such as carbon, silicon, sulfur, and phosphorus. Ferrochromium 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 low carbon (>0.15% to 0.5% C) according to the carbon content. Micro-carbon (≤0.15%C) ferrochromium. High carbon ferrochromium is also called carbon ferrochromium, and medium, low and micro-carbon ferrochromium is also called refined ferrochromium. A high-carbon ferrochromium produced from chrome ore with a low chromium-to-iron ratio, containing 50% to 55% of Cr is called charge grade ferrochromium, and nitrogen-containing ferrochromium containing N2% to 10% is used as a nitrogen alloying agent. It is called ferrochromium nitride. What are the three grades of micro-carbon ferrochromium (V10) (V6) (V3) The carbon content of the three grades is (0.1)% (0.06)% (0.03)%。
