Q275 Carbon Steel Plate is a common grade of carbon structural steel in the Chinese national standard GB/T 700 series. It is primarily designed for general purpose applications that require moderate strength and formability, making it suitable for various manufacturing and construction uses.
Composition:
Q275 carbon steel plate mainly consists of:
- Iron (Fe) as the primary element.
- Carbon (C): The main alloying element that influences its mechanical properties, with a content generally lower than high-strength steels to maintain good ductility and weldability.
- Other elements like manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), etc., are present in controlled amounts to enhance the steel's hardness, strength, and machinability while keeping the overall cost-effective.
Characteristics:
1. Moderate Strength: Q275 steel plates offer a minimum yield strength around 275 MPa, providing adequate load-bearing capacity for general-purpose applications.
2. Good Weldability: This grade has good weldability, allowing it to be easily joined by various welding methods without significant loss of strength or toughness.
3. Formability: Q275 steel exhibits satisfactory cold bending and forming properties, which makes it suitable for shaping into different forms and profiles.
4. Machinability: It offers reasonable machinability, enabling efficient cutting and machining processes.
5. Corrosion Resistance: As a carbon steel, Q275 has a relatively low resistance to corrosion compared to stainless steel; protective coatings or treatments may be required for long-term outdoor or harsh environment exposure.
Use:
Q275 Carbon Steel Plates find wide application across several industries:
1. Structural Engineering: Used in the fabrication of light-duty structures such as frames, support beams, and columns in buildings and bridges where the load requirements are not overly demanding.
2. Mechanical Components: For manufacturing parts that do not require high strength but need good formability and weldability, including machinery frames, brackets, and supports.
3. Pressure Vessels: In non-critical sections of pressure vessels and tanks where the stress levels are moderate.
4. Piping Systems: For less critical piping components and supports.
5. General Fabrication: Widely used in diverse fabrication works such as platforms, ladders, and other industrial equipment where cost-effectiveness and ease of processing are crucial.
Please note that exact specifications and properties can vary based on the manufacturer's standards and the intended use. Always refer to official material data sheets or supplier documentation for specific information about a particular Q275 carbon steel plate product.
