What are the main materials of rectangular steel tubes?

Rectangular steel tube is a commonly used steel product with the advantages of high strength, light weight, corrosion resistance, and easy processing. It is widely used in construction, machinery, electric power, chemical industry and other fields. Rectangular steel pipes are made of different materials and have different properties. The following introduces the main material types and characteristics of rectangular tubes.

1. Carbon structural steel
Carbon structural steel, also known as ordinary steel, is one of the most common rectangular steel pipe materials. Its main components are carbon, iron and small amounts of other elements, and it has sufficient strength and durability. Carbon structural steel is widely used in the production of various machinery, building structures, automobile parts, etc. The most common material standard for carbon steel rectangular steel tube is ASTM A500.

2. Alloy structural steel

Alloy structural steel contains a certain amount of alloy elements, such as chromium, manganese, molybdenum, etc. These elements can improve the hardness, strength and corrosion resistance of the material. Alloy structural steel is widely used in the production of various machinery, tools, auto parts, etc.

3. Stainless steel
Stainless steel has good corrosion resistance, high temperature resistance and aesthetics, and is one of the ideal materials for manufacturing high-quality products. When making rectangular steel pipes, the application of stainless steel can not only extend the service life, but also improve the aesthetics of the rectangular steel pipes. Stainless steel rectangular steel pipes are widely used in decoration, food processing, pharmaceutical and other fields.

4. Welded steel pipe
Welded steel pipes are made of steel plates through bending, forming, welding and other processes. There are many types of welded steel pipes, and different types of rectangular steel pipes can be selected according to the needs of different materials. Welded steel pipes are mainly used in construction, machinery, equipment manufacturing and other fields.

5. Cold drawn steel
Cold-drawn steel is a high-precision, high-strength steel product made by cold-drawing technology, with good wear resistance and corrosion resistance. Cold-drawn steel rectangular steel pipes are widely used in automotive parts, hydraulic power systems, precision machinery and other fields.

To sum up, the material types of rectangular steel tubes are very rich, and rectangular steel pipes of different materials have different applications in different fields. Choosing the appropriate rectangular steel tube material can effectively improve product quality and life.
