Ferro-alloys; ferro-silico-chromium

HS v2017 Code: 720250

About ferro-alloys; ferro-silico-chromium

HS code 720250 covers ferro-silico-chromium, a critical ferro-alloy used in the production of stainless steel and other high-performance alloys. This industry plays a vital role in the global metals and manufacturing sectors, providing essential materials for a wide range of industries, from construction and transportation to aerospace and defense.

Production process

Ferro-silico-chromium is typically produced through the smelting of chromium ore, silicon, and iron in an electric arc furnace. The high temperatures and controlled atmosphere of the furnace allow for the reduction and alloying of the raw materials, resulting in the desired ferro-alloy composition. The molten ferro-alloy is then cast into ingots or other shapes for further processing and distribution.

Production inputs

The main inputs for the ferro-silico-chromium industry include chromium ore, silicon, and iron. High-quality raw materials are essential to ensure the desired chemical composition and physical properties of the final product. Additionally, the production process requires significant amounts of electricity to power the electric arc furnaces, as well as specialized equipment and machinery for smelting, casting, and handling the molten alloy.

Production outputs

Ferro-silico-chromium is primarily consumed by the 720821 stainless steel industry, where it is used as an alloying element to improve the corrosion resistance, strength, and high-temperature performance of the final steel products. It may also be used in the production of 720229 ferro-chromium and other specialty alloys.
