Q345D Galvanized Pipe
Q345D Galvanized Pipe is a reliable and versatile product characterized by high-strength and low-alloy contents. To enhance their corrosive resistance, these pipes go through the galvanized process, coating them with thick 40-80 microns zinc material. The materials easily adhere to the surface of the steel and form strong metallurgical bonds. Generally, the hardness of the Galvanized Pipe is measured around 140-180HB with a melting point of 1420C. In Q345D the D indicates that the steel is tested for impact performance at a low temperature of -20C. The results show the toughness of the steel pipes in coldness. Elongation of this product is around 23% for pipes that are less than 15mm in thickness.

Chemically, the Q345D Galvanized Pipe consists of Nickel (0.50%), Chromium (0.35%), Carbon (0.18%), Sulfur & Phosphorus (0.030%), Copper( 0.30%), and trace amounts of Niobium. The density of the steel pipes is around 7.80g/cm3 with a yield strength of 350MPa. The zinc coating is also sacrificial as it corrodes preferentially over the steel surface. Q345D pipes are the best choice for several industrial uses. These pipes are used in structural applications such as bridges, railways, building infrastructure, industrial machinery, and outdoor structural components.
