Carbon Steel Black Square Tube 23mm: A Versatile Building Material. Carbon Steel Black Square Tube 23mm is an essential component in various construction and manufacturing applications. The Carbon Steel Black Square Tube 23mm offers excellent strength and durability, making it suitable for structural frameworks. Its square shape provides stability and rigidity, which is crucial in many projects.
The Carbon Steel Black Square Tube 23mm has a black surface and a unique texture. It can provide a different visual effect in some occasions with specific requirements for appearance without the need for additional color treatment.
Carbon Steel Black Square Tube 23mm is mainly used in building support.
Strength: carbon steel itself has a high strength, 23mm carbon steel black square tube can withstand a certain pressure and external force, such as in the building structure can be used as a supporting part to bear a certain weight. Generally, the yield strength of Q235 carbon steel is not less than 235MPa, and the tensile strength is between 375-500MPa.
Toughness: With good toughness, in the impact or vibration, can absorb a certain amount of energy, reduce the risk of rupture or fracture. For example, in mechanical vibration environments, structural integrity is maintained and the probability of damage is reduced.
Hardness: moderate hardness, can meet the general wear and deformation requirements. Depending on the carbon content, the hardness is relatively higher when the carbon content is higher, and it can resist wear and scratching to a certain extent.
