Chain; articulated link, roller, of iron or steel

HS code 731511 covers the classification of articulated link, roller chains made of iron or steel. These chains are essential components in a wide range of industrial and commercial applications, from agricultural machinery to material handling equipment. As a critical part of many power transmission systems, the 731511 chain industry plays a vital role in supporting the broader manufacturing and logistics sectors of the global economy.

The production of 731511 roller chains typically involves a multi-step process. First, the individual chain links are stamped or forged from high-quality steel alloys. The links are then heat-treated to improve their strength and durability. Next, the links are assembled into the desired chain configuration, with the roller elements added to facilitate smooth operation. Finally, the completed chains may undergo additional finishing processes, such as plating or coating, to enhance their corrosion resistance and aesthetic appeal.

The main inputs required for the 731511 chain industry include steel raw materials, specialized machinery for stamping and assembly, and various lubricants and coatings. High-grade steel alloys, such as carbon steel or stainless steel, provide the necessary strength and corrosion resistance for the chain links. Automated stamping and assembly equipment help to ensure consistent quality and efficient production. Lubricants and protective coatings are also essential to maintain the chains' performance and lifespan.

The primary output of the 731511 chain industry is, of course, the articulated link, roller chains themselves. These chains are widely used in a variety of applications, including 842833 Lifting, handling, loading or unloading machinery, 842952 Machinery for processing or working of wood, cork, bone, hard rubber, hard plastics or similar hard materials, and 843149 Parts suitable for use solely or principally with the machinery of headings 8425 to 8430. The 731511 chains may also be consumed by industries producing 842890 Machinery for lifting, handling, loading or unloading, n.e.s. and 848340 Gears and gearing, other than toothed wheels, chain sprockets and other transmission elements presented separately; ball or roller screws; gear boxes and other speed changers, including torque converters.
