In the common material of spiral steel pipes, the strength of Q345B is primarily reflected in the following aspects:
Tensile Strength: The tensile strength of Q345B is 370~500 N/mm², while Q235B's is only 230~340 N/mm². This means Q345B has a higher tensile strength than Q235B.
Yield Strength: The yield strength of Q345B is ≥320 MPa, while that of Q235B is ≥195 MPa. This means the yield strength of Q345B is higher than that of Q235B.
Tensile Elongation: The elongation rate of Q345B is ≥19%, while that of Q235B is ≥21%. Although the difference is not significant, it still indicates that Q345B has better plastic deformation capability.
In summary, among the common materials for spiral steel pipes, the strength of Q345B.
Shunde Longyao Iron and Steel Co., Ltd. in Foshan was established on May 11, 2015. The legal representative is Huang Songming, and the company is engaged in the sale of steel and domestic commerce.
Spiral steel pipes can be categorized differently based on various classification criteria. The following are several common methods of classification:
Categorized by pipe type: General Welded Spiral Steel Pipe, X80 Large Diameter High Strength Spiral Steel Pipe, Alloy Spiral Steel Pipe. Categorized by diameter: Large Diameter Spiral Steel Pipe and Small Diameter Spiral Steel Pipe. Categorized by wall thickness: Thick-Walled Spiral Steel Pipe and Thin-Walled Spiral Steel Pipe. Categorized by specification: Such as 219 Spiral Steel Pipe, 273 Spiral Steel Pipe, 325 Spiral Steel Pipe, 529 Spiral Steel Pipe, 630 Spiral Steel Pipe, etc. Categorized by material: Q235B Spiral Steel Pipe, Q345B Spiral Steel Pipe, X60 Spiral Steel Pipe, etc. Spiral steel pipes of different types have various characteristics and applications, and the appropriate type can be selected based on the actual usage scenario.
