Product Description
 What is Q345B?

Q345 is a steel material. It is low-carbon steel (c <0.2%), good overall performance, good low temperature performance, the performance of cold stamping, welding performance and good cutting. Widely used in bridges, vehicles, ships, construction, pressure vessels. Q represents the yield of this material, behind the 345, the yield refers to the value of this material around the 345MPa. And will increase the thickness of the material and its yield value decreases.
By the Q + digital + quality rating symbols + deoxy method symbols. Its steel dubbed "Q", the representative of the yield point of steel, behind the numbers indicate the yield point value, the unit is MPa yield point such as Q235 (σs) of 235 MPa of carbon structural steel.

Standard: GB/T1591-2008

Advantage: Good low temperature performance, cold stamping performance

Higher grade: Q345C,Q345D,Q345E
