Q345C steel plate is a low alloy structural steel. "Q" means yield strength, and the yield strength of Q345C steel plate is not less than 345 MPa.
The construction process of Q345C steel plate welding is groove preparation → spot welding → preheating → internal welding → back root cleaning (carbon arc gouging) → external welding → internal welding → self-inspection / special inspection → Post-weld heat treatment → non-destructive inspection (welding seam quality first grade qualified).
Q345C steel plate belongs to welded structural steel, which is a kind of steel widely used in manufacturing industry. Q345C steel plate is widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment, etc. Q345C steel plate is used for pressure vessel or steel structure, such as making large storage tank, H-shaped steel, vehicle frame, etc.
