Excellent mechanical properties: Cold-rolled steel strip is produced through cold rolling process, with high strength and good stability, which can improve the bearing capacity and safety of the structure. Excellent surface quality: The surface is flat and smooth, with high dimensional accuracy, which makes the cold-rolled steel strip have great advantages in appearance and is suitable for products that require fine processing
Q235B/Q355B steel strip is a carbon structural steel with excellent weldability, plasticity and toughness, and is widely used in construction, rail transportation, mechanical equipment and other fields. Its characteristics: strength and mechanical properties, corrosion resistance, machinability and weldability.
Surface treatment: divided into three types of finishing surfaces according to precision: higher grade (FB), higher grade (FC), and super higher grade (FD) Derivative forms: In addition to steel strips/sheets, it can also be processed into bars, welded pipes, flanges and other structural parts International benchmarking: There is technical interoperability with the German DIN standard ST13 series
Specifically, these numbers represent the level of deep drawing performance. The larger the number, the better the deep drawing performance of the material. DC01 is a common material, not suitable for stretching, and only suitable for simple bending. DC02 can be used for shallow stretching, but is usually limited to bending. DC03 is called a stretching plate, and DC04 has the best stretching performance among the four materials and is suitable for deep drawing.
Both ST12 and ST14 are cold-rolled steels, but their application levels and mechanical properties are different. ST12 is the most common steel grade, which is basically the same as q195, SPCC, and DC01 grades. The yield strength of ST12 is aMPa≤280; the tensile strength is MPa≤270～410; the elongation after fracture (L0=80mm, b=20mm)%≥28. ST14 is a deep-drawing grade cold-rolled steel, which means it can withstand greater deformation without breaking, and is suitable for occasions with higher requirements for ductility.
DX51D/52D/53D/54D/56D steel strips generally have good corrosion resistance and are suitable for use in various environments. Processing performance: They have good stamping and welding properties, making them easy to process into various shapes and structures. Economical: Compared with other types of steel, these steel strips may have better cost-effectiveness
