Iron or non-alloy steel; flat-rolled, cold-rolled, of a width less than 600mm, containing by weight 0.25% or more of carbon

HS v2022 Code: 721129

About iron or non-alloy steel; flat-rolled, cold-rolled, of a width less than 600mm, containing by weight 0.25% or more of carbon

HS code 721129 covers a specific type of cold-rolled steel product that is widely used in various industries. This flat-rolled steel, containing at least 0.25% carbon by weight, is an essential material for manufacturing a range of components and parts. Its unique properties, such as high strength and durability, make it a valuable commodity in the global steel trade and a crucial input for many downstream 731500 Manufacture of other fabricated metal products, 732300 Manufacture of steam generators, except central heating hot water boilers, and 722220 Manufacture of steel tubes, pipes and hollow profiles.

Production process

The production of HS code 721129 steel involves a series of cold-rolling processes. First, the steel is heated and then passed through a series of rollers that gradually reduce the thickness of the material, resulting in a flat, thin sheet. This cold-rolling process enhances the steel's strength and surface finish without significantly altering its chemical composition. The final product is then cut to the desired width and packaged for distribution.

Production inputs

The main inputs required for the production of HS code 721129 steel include iron ore, coal, and scrap metal. These raw materials are smelted in a blast furnace to produce molten pig iron, which is then further refined and alloyed to achieve the desired carbon content and other properties. Specialized rolling mills, annealing furnaces, and cutting equipment are also essential for the cold-rolling and finishing processes.

Production outputs

HS code 721129 steel is a versatile material that finds applications in a wide range of industries. It is commonly used in the manufacture of 731500 Manufacture of other fabricated metal products, such as automotive parts, household appliances, and construction materials. Additionally, this steel is often consumed by the 732300 Manufacture of steam generators, except central heating hot water boilers and 722220 Manufacture of steel tubes, pipes and hollow profiles industries, where its strength and durability are highly valued.
