| Common materials and corresponding specifications of carbon steel coil sheet |
| The specifications of carbon steel coil plates need to be determined comprehensively based on the material properties, thickness, width and processing requirements. The following are the main types and specifications for reference: Common carbon structural steel coil Represented by the Q235 series, such as Q235B, Q235C, etc., it is widely used in fields like construction and mechanical manufacturing. Its specifications cover thickness ranging from 10mm to 500mm, and width can be customized up to 200mm to 8000mm. It supports processing methods such as laser cutting and flame cutting, and can meet the customized requirements for different geometric shapes 13. Low alloy high strength carbon steel coil Typical example is 16Mn (Q345), which belongs to low alloy structural steel, with grades A, B, C, D, and E. It has excellent welding performance and is suitable for pressure vessels, metal structural components, etc. The thickness range is usually 8mm to 500mm, and the raw materials are mostly from steel mills like Baosteel and Shaogang, etc. It can be processed into precise dimensions through processes such as shearing machines and CNC cutting 23. Special purpose carbon steel coil Wear-resistant carbon steel coil: such as NM360-NM600 series, the thickness specifications vary according to the wear resistance grade, commonly 8mm to 26mm, suitable for high-strength wear scenarios in mining machinery, crusher linings, etc. 13. Weathering carbon steel coil: including Q235GNH, Q345NH, etc., it has the characteristic of resisting atmospheric corrosion, with specifications covering regular thicknesses above 8mm, and width can be customized according to project requirements, often used in bridges, outdoor structural components 13. |
