High carbon ferrosilicon is added to steel to increase its strength and hardness. Its high carbon content also makes it useful in the production of specialty steels, such as those used in the automotive and tool industries.
The price of high carbon ferrosilicon varies depending on factors such as global supply and demand, production costs, and market conditions. As of March 2023, the price of high carbon ferrosilicon is around $1,000 - $1,500 per metric ton.
