Q275 Carbon Steel Plate
Q275 Carbon Steel Plate is a Chinese national standard (GB/T 700) grade of general structural carbon steel. The "Q" stands for Yield Strength, and "275" indicates a guaranteed minimum yield strength of 275 MPa (for plates 16 mm thick). This steel offers a good balance of moderate strength, good ductility, excellent weldability, and desirable toughness. It is widely used in construction, bridges, machinery, general engineering, and manufacturing for structural components, welded assemblies, and general purpose structural elements where the specified strength and reliable performance are required.
