Q235 vs. Q345 Steel Plate (How to Distinguish) MachineMfg
Distinguish Q345 and Q235 B methodAccording to the color of the steel plate, the Q235 and Q345 materials can be distinguishedthe color of Q235 is blue, and the Q345 is red (this is only for the steel that just came into the market, and if the time is long then it also cannot be distinguished).
What is Q235 & Q345 steel? – Shean's Iron and Steel Solution
Q345 has a tensile strength range of 490-675 Mpa, while the Q235 has a 375-500 Mpa range. Q345 has a yield strength of ≥ 345 Mpa, while the Q235 has a ≥ 235 Mpa. Q345 has an elongation rate after fracture of ≥ 21%, while the Q235 has ≥ 26%. There may be some end users who question the quality and the reliability of these steel types.
Q235 vs Q345 Strength? - Structural engineering general
Sep 28, 2010 · The Q345 is stronger as bones206 noted. That means that it has a higher yield stress and higher tensile strength. Its stiffness (Young's modulus) should be about the same as the Q235 however.
