Q195 Q215 Q235 Q275 Welded carbon steel pipe Carbon steel square pipe

The high quality Q195, Q215, Q235 and Q275 welded carbon steel pipes and carbon steel square pipes are a series of steel products made from high-quality raw materials and advanced production processes. These materials are widely used in many fields such as building structure and machinery manufacturing, and are favored for their good mechanical properties and processing characteristics.

Q195: This is a low-carbon structural steel, with good plasticity and toughness, easy to process molding, but the strength is relatively low, suitable for making parts or components with low strength requirements.

Q215: Compared to Q195, Q215 contains a slightly higher carbon content, so its hardness and strength are increased, while maintaining a certain ductility and weldability, suitable for the manufacture of parts working under moderate loads.

Q235: As one of the most commonly used ordinary carbon structural steels, Q235 not only has high tensile strength, but also has good comprehensive mechanical properties, such as high yield point, good impact toughness, etc., which is very suitable for the production of various types of steel structural parts.

Q275: Compared to the first three, Q275 is a higher grade of carbon structural steel, which provides a higher level of strength, but also means that it may sacrifice some plasticity and toughness. Nevertheless, this material is still the ideal choice in the case of the need to withstand a large external force.

All of these types of welded carbon steel pipes and square pipes undergo a strict quality control process to ensure that each batch of products can meet or even exceed the requirements of industry standards. They are widely used in bridge construction, high-rise building frames, vehicle manufacturing and other industries, providing a solid foundation for the safety and stability of engineering projects. In addition, thanks to the use of advanced welding technology, these pipes are tightly connected without gaps, further enhancing the reliability and durability of the overall structure.
