In the modern steel industry, the addition of alloying elements is essential to improve the performance of steel. Chromium, as an important alloying element, can significantly improve the corrosion resistance, wear resistance and high-temperature performance of steel. Low-carbon ferrochrome, with high chromium and low carbon, ensures the chromium content and controls the carbon content. It is an effective alloy additive for smelting stainless steel, alloy steel and special steel.

Ferrosilicon alloy is mainly composed of iron and silicon, and the silicon content is usually between 15% and 90%, which varies according to different application requirements and standard specifications.
