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

HS v2022 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 known for its high strength, durability, and resistance to wear and corrosion, making it a crucial material in various industrial applications. The global silico-manganese steel industry plays a significant role in supporting the growth and development of sectors such as construction, automotive, machinery, and infrastructure.

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 in a furnace to create the desired steel alloy. The molten steel is then cast into ingots or continuous cast into billets or blooms. These semi-finished products are then reheated and rolled or forged into the final shape of bars and rods, which can be further processed through heat treatment, straightening, and cutting to meet specific customer requirements.

Production inputs

The key inputs for the production of silico-manganese steel bars and rods include iron ore, manganese, and silicon as the primary raw materials. Additionally, the industry relies on specialized machinery and equipment, such as electric arc furnaces, continuous casting machines, and rolling mills, to facilitate the various stages of the production process. Energy sources, such as electricity and natural gas, are also essential inputs for the melting, casting, and rolling operations.

Production outputs

The primary output of HS code 722820 is silico-manganese steel bars and rods, which are widely used in a variety of industries. These products may be consumed by manufacturers of 731100 Structures and parts of structures, of iron or steel; plates, rods, angles, shapes, sections, tubes and the like, prepared for use in structures, 732410 Sanitary ware and parts thereof, of iron or steel, and 842199 Parts of machinery for filtering or purifying liquids or gases, among others. The versatility and strength of silico-manganese steel make it a valuable material for applications that require high-performance and durable components.
