Usage:

(1) Used as an alloying agent for ball steel, tool steel, and high-speed steel with high carbon content, to improve the hardenability of steel, increase its wear resistance and hardness;

(2) Used as an additive for cast iron to improve its wear resistance and hardness, while also giving it good heat resistance;

(3) Used as a chromium containing raw material for the production of silicon chromium alloys and medium, low, and micro carbon ferrochrome using slag free method;

(4) Used as a chromium containing raw material for electrolytic production of metallic chromium;

(5) Used as a raw material for oxygen blowing smelting of stainless steel.
