Q345C Structural Steel

Overview:
Q345C is a high-strength carbon structural steel in China, classified under GB/T 1591. It offers higher yield strength than Q235B and is slightly lower than Q345B, with excellent mechanical properties and good weldability. Q345C is suitable for structural applications requiring moderate strength with reliable ductility.

Key Features:

High-strength carbon steel with good ductility and toughness
Excellent weldability and machinability for structural fabrication
Yield strength of 345 MPa minimum
Consistent mechanical properties suitable for medium-load construction and engineering applications

Delivery Condition:
Q345C is typically supplied in hot-rolled plates, sheets, bars, or structural sections. It can be delivered in standard dimensions or cut-to-length according to client specifications. The steel is ready for welding, machining, or fabrication in structural components.

Applications:

Medium-load structural frameworks for buildings, bridges, and industrial plants
Engineering machinery and equipment requiring moderate strength
Steel fabrication projects with welding and machining requirements
Beams, columns, and reinforcements in construction and engineering projects

Conclusion:
Q345C is a reliable structural steel option, balancing strength, weldability, and ductility. It is widely used in construction, industrial, and engineering projects where dependable performance is essential. For moderate-load structures, Q345C provides a cost-effective and high-quality solution.
