Nitrided ferro chrome (FeCrN) is a type of ferro chrome alloy that has been enriched with nitrogen. It is made by adding nitrogen gas into the solid ferro chrome during production. The nitrogen reacts with the chrome and iron to form a stable nitride compound that is incorporated into the alloy.
Nitrided ferro chrome is used as a high-performance alloy that offers improved properties such as increased hardness, toughness, and wear resistance. It is commonly used in the production of stainless steel, as well as in the manufacturing of cutting tools, dies, and wear parts. Nitrided ferro chrome can also be used as a substitute for costly materials like titanium and nickel, making it an attractive option for many industries.
Nitrided Ferro Chrome Production
Nitrided Ferro Chrome (FeCrN) is a type of ferroalloy that is produced by the electric arc furnace method, where chrome ore is smelted along with a blend of other raw materials such as iron, silicon, and nitrogen. The process involves the reaction of chrome ore, carbonaceous reduction agents, and nitrogen gas to produce a product with a high nitrogen content. Nitrided Ferro Chrome is mainly used in the production of stainless steel and other specialty steels.
The specification of Nitrided Ferro Chrome typically includes a nitrogen content ranging from 6% to 12%, with a preferred range of 8% to 10%. The carbon content is typically around 0.1% to 0.3%, and the silicon content is generally around 1% to 3%.
The Uses of Nitrided Ferro Chrome
The buyers of Nitrided Ferro Chrome are primarily steel manufacturers who use the alloy as a feedstock in the production of high-strength and corrosion-resistant stainless steel. Nitrided Ferro Chrome is also used as a grain refiner in cast iron production, as well as a component in certain types of welding electrodes.
The production process for Nitrided Ferro Chrome involves several steps. The raw materials, including chrome ore, iron ore, silicon, and carbonaceous reduction agents, are preheated in a furnace before being charged into an electric arc furnace. The furnace is then heated, and an electric arc is generated between electrodes, creating high temperatures of around 2,800 to 3,000 degrees Celsius. The resulting product is then tapped and poured into a ladle, and nitrogen gas is injected to form Nitrided Ferro Chrome. The alloy is then crushed, screened, and packaged for shipping. The entire process can take up to several hours, depending on the size of the furnace and the production rate required.
