Q345C Steel Description

Q345C low carbon alloy steel has lower low temperature impact test temperature (impact temperature is 0 degrees) and has good performance. Compared with Q345A and Q345B steel, The content of harmful substances P and S is lower than that of Q345A and B. Q345C steel is a low-alloy structural steel with a yield strength of not less than 345 MPa. The original grade is 16Mn. It is a welded structural steel and is widely used in the manufacturing industry. Q345C steel plate is mainly used for the production of pressure vessels or steel structures, such as the production of large storage tanks, H-beams, vehicle skeletons, etc.

Q345C carbon and low alloy steel plate refers to high strength, especially in normalized or normalized and tempered state, with high comprehensive mechanical properties. Q345C steel plate is a kind of weldable low-carbon engineering structural material, which is generally produced by continuous rolling mills. Its carbon content is less than 0.25%, mainly due to the solid solution of alloying elements (Mn, Si, Al, Cr, etc.), grain refinement (Nb, V, Ti, etc.), precipitation hardening (Nb, V, Ti, etc.) , phase transformation strengthening (Mn, Si, Mo, etc.) and new processes and technologies such as controlled rolling and controlled cooling, the yield strength of Q345C steel plate is σ0.2=300~800MPa, the yield strength ratio is 0.65~0.95, and has Good formability and weldability, as well as excellent low temperature toughness.
