Among the commonly used spiral steel pipe materials, the strength of Q345B is mainly reflected in the following aspects:
Tensile Strength: The tensile strength of Q345B is 370~500 N/mm², whereas Q235B's tensile strength is only 230~340 N/mm². This indicates that Q345B has a higher tensile strength than Q235B.
Yield Strength: The yield strength of Q345B is ≥320 MPa, while Q235B's yield strength is ≥195 MPa. This means that 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 in elongation rates is not significant, it still indicates that Q345B has better plastic deformation capability.
In summary, among common spiral steel pipe materials, Q345B has a high strength.
