Iron or non-alloy steel; flat-rolled, width 600mm or more, plated or coated with chromium oxides or with chromium and chromium oxides

HS v2017 Code: 721050

About iron or non-alloy steel; flat-rolled, width 600mm or more, plated or coated with chromium oxides or with chromium and chromium oxides

HS code 721050 covers a crucial category of flat-rolled steel products that are plated or coated with chromium oxides or a combination of chromium and chromium oxides. These materials are widely used in various industries, including automotive, construction, and consumer goods, due to their enhanced corrosion resistance, durability, and aesthetic appeal. As a key component of the broader steel industry, this product group plays a significant role in supporting global manufacturing and infrastructure development.

Production process

The production of HS 721050 steel involves a multi-step process. First, iron or non-alloy steel is rolled into flat sheets or strips with a width of 600mm or more. These flat-rolled products are then subjected to a plating or coating process, where they are covered with a layer of chromium oxides or a combination of chromium and chromium oxides. This surface treatment enhances the steel's resistance to corrosion and improves its visual appearance, making it suitable for a wide range of applications.

Production inputs

The main inputs required for the production of HS 721050 steel include iron or non-alloy steel as the primary raw material, as well as chromium and other necessary chemicals for the plating or coating process. Additionally, specialized rolling and coating equipment, such as rolling mills and chromium plating lines, are essential for the manufacturing of these flat-rolled steel products.

Production outputs

The primary output of HS 721050 is flat-rolled steel sheets or strips that are plated or coated with chromium oxides or a combination of chromium and chromium oxides. These materials are widely used in the production of 721090 Iron or non-alloy steel; flat-rolled, width 600mm or more, plated or coated, 730810 Structures and parts of structures; iron or steel, n.e.c. in heading no. 7308, and 732393 Table, kitchen or other household articles and parts thereof; of stainless steel.
