The carbon equivalent of Q355D steel plate is 0.41%. The calculation formula for carbon equivalent is:
Carbon Equivalent = C + Mn/6 + (Ni + Cu)/15 + (Cr + Mo + V)/5,
where the symbols represent the weight percentage of each element. A lower carbon equivalent indicates better welding performance; specifically, a carbon equivalent ≤ 0.35 indicates good welding performance, while a carbon equivalent of ≥ 0.4 to 0.5 indicates more difficult welding.
