Ferrosilicon grades and chemical composition

Oct 30, 2023 Leave a message

Ferrosilicon has a wide range of applications and can be used to deoxidize steel, incubate iron to accelerate graphitization, and change steel properties.

 

Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel, therefore, ferrosilicon is also used as alloying agent in smelting structural steel (0.40-1.75% silicon) , tool steel (30-1.8% silicon) , spring steel (40-2.8% silicon) and transformer steel (2.81-4.8% silicon) . It is an effective new technology to improve the quality of steel, reduce the cost and save the use of iron by improving the morphology of inclusions and reducing the content of gas elements in molten steel
