Steel, alloy; bars and rods, of silico-manganese steel

HS v2017 Code: 722820

About steel, alloy; bars and rods, of silico-manganese steel

HS code 722820 covers the import and export of steel alloy bars and rods made from silico-manganese steel. This type of steel is prized for its high strength, durability, and resistance to corrosion, making it a critical material in a wide range of industrial applications. The global trade in silico-manganese steel bars and rods is a significant component of the broader steel industry, which is a fundamental pillar of the world economy.

Production process

The production of silico-manganese steel bars and rods typically involves a multi-step process. First, the raw materials, including iron ore, manganese, and silicon, are melted together in a furnace to create the desired steel alloy. The molten steel is then cast into ingots or continuous cast into billets, which are subsequently rolled or forged into the final bar or rod shapes. Heat treatment and other finishing processes may be applied to enhance the steel's mechanical properties and surface finish.

Production inputs

The main inputs required for the production of HS code 722820 products include iron ore, manganese, and silicon as the primary raw materials. Additionally, the industry relies on specialized steelmaking equipment such as electric arc furnaces, continuous casting machines, and rolling mills. Energy sources, such as electricity and natural gas, are also crucial inputs for the high-temperature manufacturing processes involved.

Production outputs

The primary output of HS code 722820 is silico-manganese steel bars and rods, which are used in a variety of industries. These products may be further processed or incorporated into the manufacturing of other goods, such as 730120 Steel, alloy; angles, shapes and sections, of silico-manganese steel, 730210 Steel, alloy; rails for railway or tramway tracks, and 730840 Steel, alloy; tubes, pipes and hollow profiles, seamless, among others.
