Angle Iron Product Description
Q195 is a carbon structural steel with a yield strength of 195MPA. It has high plasticity, toughness, welding performance, and good pressure processing performance. Used to manufacture anchor bolts, plowshares, chimneys, roof panels, rivets, low carbon steel wires, sheets, welded pipes, tie rods, hooks, brackets, welded structures, etc.
Q235 is a low carbon steel with a carbon content of about 0.2%. It has high plasticity and good welding performance. However, its strength is low and it is suitable for drawing and rolling processing, such as making profile plates, etc.
Q345 is a steel material. It is low alloy steel (C<0.2%) and is widely used in buildings, bridges, vehicles, ships, pressure vessels, etc. Q represents the yield strength of this material, and the following 345 refers to the yield value of this material, which is around 345 MPa. And as the thickness of the material increases, its yield value decreases.
