Types of Ferrochromium
1. High-carbon ferrochrome
High-carbon ferrochrome is usually used as an alloying agent for ball steel (0.5%～1.45%Cr), tool steel, die steel (5%～12%Cr), and high-speed steel (3.8%～4.4%Cr), and can harden steel. Increase the wear resistance and hardness of steel.
2. Medium and low-carbon ferrochrome
Medium and low-carbon ferrochrome is used in the production of medium and low-carbon structural steel, carburizing steel, gears, high-pressure blower blades, valve plates, etc.
3. Micro-carbon ferrochrome
Micro-carbon ferrochrome is mainly used to produce stainless steel, wear-resistant steel, and heat-resistant steel.
