Carbon Square Tube
Carbon steel square tube is a square cross-section tube made of carbon steel with the following characteristics:
1. Material
Carbon steel: The main components are iron and carbon, and the carbon content is usually between 0.04% and 2.0%. It may also contain a small amount of manganese, silicon and other elements.
2. Manufacturing process
Hot rolling: Rolling at high temperature, suitable for large-sized, thick-walled tubes.
Cold drawing: Stretching at room temperature, suitable for small-sized, thin-walled tubes, with smoother surface and more precise size.
3. Specifications
Size: The side length ranges from a few millimeters to hundreds of millimeters.
Wall thickness: From thin wall to thick wall, there are various choices.
4. Characteristics
High strength: Good tensile and compressive resistance.
General corrosion resistance: Easy to rust, surface treatment is required.
Good machinability: Easy to weld, cut, and bend.
5. Application
Construction: Used for steel structures, brackets, etc.
Machinery manufacturing: Used for mechanical frames and conveying equipment.
Automobile: Used for frames and chassis.
Furniture: used for tables, chairs, and shelves.
6. Surface treatment
Galvanizing: improves corrosion resistance.
Painting: prevents rust and improves appearance.
Polishing: improves surface finish.
7. Advantages
Low cost: relatively cheap.
High strength: suitable for load-bearing structures.
Easy to process: easy to weld and cut.
8. Disadvantages
Easy to rust: requires anti-rust treatment.
Heavy weight: heavier than aluminum alloy and other materials.
Carbon steel square tubes are widely used in construction, machinery, automobiles, furniture and other fields due to their high strength, low cost, and easy processing.
