High carbon ferro Chrome is the most important raw material for stainless steel production. It is mainly used in the production of stainless steel, ball bearing steel, tool steel, nitriding steel, heat-strength steel, quenched and tempered steel, carburizing steel and hydrogen-resistant steel. Because chromium plays a decisive role in stainless steel, there is only one element determining the attributes of stainless steel, that is, chromium. Each stainless steel must contain a certain amount of chromium.
The corrosion resistance of stainless steel mainly comes from chromium. Experiments show that only when the content of chromium exceeds 12%, the corrosion resistance of steel will be greatly improved. Therefore, the content of chromium in stainless steel is generally not less than 12%. Therefore, the supply and demand situation of chromite is closely related to the supply and demand situation of stainless steel market.
High carbon ferrochromium is used as alloying agent for ball steel, tool steel and high speed steel with high carbon content to improve hardenability, wear resistance and hardness of steel; as additive for cast iron to improve wear resistance and hardness of cast iron, and to make cast iron have good heat resistance; as chromium-containing raw material for slag-free production of silicon-chromium alloy and medium, low and micro-carbon ferrochromium; as electrolytic production. A chromium-containing material of metallic chromium; used as a raw material for the smelting of stainless steel by oxygen blowing.
