HS v2017 Code: 722920

About steel, alloy; wire, of silico-manganese steel

HS code 722920 covers the trade of steel alloy wire made from silico-manganese steel. This type of steel is known for its high strength, durability, and resistance to corrosion, making it a popular choice for a wide range of industrial applications. The silico-manganese steel wire industry plays a crucial role in supporting various manufacturing sectors, from construction and infrastructure to automotive and machinery production.

Production process

The production of silico-manganese steel wire typically involves a multi-step process. First, the raw materials, including iron, manganese, and silicon, are melted and alloyed in a furnace to create the desired steel composition. The molten steel is then cast into billets or ingots, which are subsequently rolled or drawn into wire of the required diameter and length. Finally, the wire may undergo additional heat treatment or surface finishing processes to enhance its properties and meet specific customer requirements.

Production inputs

The main inputs for the production of silico-manganese steel wire include iron ore, manganese ore, and silicon-containing materials, such as ferrosilicon. Additionally, the industry relies on specialized machinery and equipment for melting, casting, rolling, and drawing the wire. Energy sources, such as electricity or natural gas, are also essential for the various stages of the production process.

Production outputs

The primary output of HS code 722920 is silico-manganese steel wire, which is used in a variety of applications. This wire may be further processed or incorporated into other products, such as 731210 Steel wire, ropes, cables, plaited bands, slings and the like, 731300 Barbed wire of iron or steel; twisted hoop or single flat wire, barbed or not, and loosely twisted double wire, of a kind used for fencing, of iron or steel, and 732690 Other articles of iron or steel. The versatility of silico-manganese steel wire makes it an essential component in many industries, contributing to the overall growth and development of the global economy.
