material Q345 steel is a carbon alloy steel (c<0.2%) with good comprehensive properties, good low temperature performance, good cold stamping performance, good welding performance and machinability.
material Q345 steel is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.
"Q "represents the yield of this material, and "345" in the back refers to the yield value of this material, which is around 345MPa. And will decrease the yield value as the thickness of the material increases.
q345b low alloy high strength steel plates are equivalent to DIN 17100 S355JR, ASTM A572Gr.50, EN10025-2 S355JR etc.
