Ferro Chromium

Ferro chromium is a metallurgical alloy with chromium and iron as the main components. It is silver-gray to dark gray in block or granular form, with high hardness and excellent high temperature resistance. This product is made of chromium ore, coke, and silica, and is smelted by submerged arc furnace or electric silicon thermal method. The chromium content covers 50%-75%, and the carbon content can be precisely controlled. It has the characteristics of strong alloying, corrosion resistance, and cost optimization. It is an irreplaceable key raw material in the fields of stainless steel, special alloy steel, heat-resistant materials, surface engineering, etc., and is known as the "backbone of stainless steel." ferro chromium is used in stainless steel manufacturing to provide chromium elements and form a passivation film to enhance corrosion resistance. It is used in chemical equipment, automobile exhaust pipes, medical equipment, etc. ferro chromium is used in alloy steel production to improve the hardness and toughness of structural steel. It is suitable for high-end mechanical parts such as bearing steel, gear steel, and mold steel. In the foundry industry, ferro chromium is used as an alloy strengthener for wear-resistant castings (such as ball mill liners and crusher hammers). ferro chromium in high-temperature alloys can be used for gas turbine blades and rocket engine heat-resistant parts to resist extreme oxidizing environments. Ferro chromium is used for welding rod coating to improve the corrosion resistance and process stability of weld metal.
