Q345C steel is a low-alloy structural steel with a yield strength of not less than 345 MPa, Q means yield strength, and Q345 means that the yield strength of this steel is 345 MPa.
The designation method of low-alloy high-strength structural steel is basically the same as that of carbon structural steel. It is suitable for the manufacture of large-scale steel structures for construction, bridges, ships, vehicles, railways, high-pressure vessels, boilers, automobiles, tractors, and large-scale military projects.
Q345C steel plate is a piece of steel widely used in the manufacturing industry. Q345C steel plates are mainly used for pressure vessels or steel structures, such as making large storage tanks, H-beams, vehicle frames, etc.
