Alloy steel powders

HS v2017 Code: 720521

About alloy steel powders

HS code 720521 covers alloy steel powders, which are an essential raw material for a wide range of manufacturing industries. Alloy steel powders are produced through specialized metallurgical processes and are used in the production of various components, tools, and equipment. This industry plays a crucial role in supporting the growth and development of sectors such as 731 Machinery, 732 Electrical machinery and equipment, and 871 Optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus.

Production process

Alloy steel powders are typically produced through a process called powder metallurgy. This involves the compaction and sintering of metal powders, which are then shaped and heat-treated to achieve the desired properties. The specific production techniques may vary depending on the alloy composition and the intended application of the final product.

Production inputs

The main inputs required for the production of alloy steel powders include various metal alloys, such as iron, chromium, nickel, and molybdenum. Additionally, specialized machinery and equipment, such as powder compaction presses and sintering furnaces, are essential for the manufacturing process. The production of alloy steel powders also requires a skilled workforce with expertise in metallurgy and powder processing.

Production outputs

Alloy steel powders produced under HS code 720521 are used in the manufacture of a wide range of products, including 732 Electrical machinery and equipment, 871 Optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus, and 731 Machinery. These powders are also used in the production of cutting tools, wear-resistant components, and other specialized industrial applications.
