Galvanized Steel Pipe Description
Q represents the yield point, so the yield strength ranking of these three steels is Q195, which has a yield strength smaller than Q235 and smaller than Q345. Q195 is a kind of carbon-structural steel. Used in buildings, structures, motorcycle frames, etc. Q235 is an ordinary carbon structural steel. When welded, galvanized steel Q235 pipe does not require any specific process treatment, such as preheating or post-weld heat treatment. It has a strong practical effect, a reasonable price, and high-cost performance. Q345 is a low alloy steel commonly used in automobiles, bridges, ships, and construction.
