Fecr

Fecr is an iron alloy with chromium and iron as the main components. It also contains impurities such as carbon, silicon, sulfur, and phosphorus. It is one of the main alloying agents in the steel industry and is widely used in metallurgy, refractory materials, and chemical industries. It is an iron-based alloy with a chromium content of 50%-70%, a small amount of carbon, silicon, etc. It is divided into high, medium, and low carbon types according to the carbon content. It is a core additive in the metallurgical industry. It can improve the corrosion resistance, hardness, and high-temperature oxidation resistance of steel. It accounts for 60%-80% in stainless steel production. It is made by reducing chromium ore and smelting coke in an electric furnace. It has controllable costs and stable composition. It is used in the manufacture of high-end corrosion-resistant materials.
Fecr is composed of chromium and iron. It is smelted in a submerged arc furnace and has high hardness, wear resistance, and oxidation resistance. It is used in the production of stainless steel, heat-resistant steel, and tool steel. It can improve the corrosion resistance and hardenability of steel. In the foundry industry, it can enhance the wear resistance and hardness of castings. It is an essential material for the steel industry.
Fecr alloys produced by electro-silicon thermal method or vacuum decarburization process have a precise chromium-iron ratio. High-carbon type is used for wear-resistant cast iron, and low-carbon type is used for ultra-pure stainless steel and aviation alloys. It can generate chromium oxide film to delay the corrosion of steel, refine grains and improve strength. Fecr is a key raw material for anti-corrosion coatings, combining performance and durability.
