Q345D seamless pipe is a kind of seamless steel pipe, which has good comprehensive mechanical properties, low temperature impact toughness, cold stamping and cutting processability, weldability.

Q in Q345D seamless pipe is the abbreviation of yield strength, 345 is the yield strength value, that is, the yield strength of Q345D seamless pipe is 345 MPa, and D is the low temperature impact temperature, which is - 20 ℃.

Q345D seamless pipe is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc.
