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
Features of ribbed steel bars: Firm connection: The ribs of ribbed steel bars can strengthen the adhesion between the steel bars and concrete, improve the connection force, have higher tensile properties, and are conducive to the safety and reliability of engineering structures. Strong earthquake resistance: Ribbed steel bars have better earthquake resistance, which can ensure that the project still has good bearing capacity when a strong earthquake occurs. Wide range of application: Ribbed steel bars are widely used in various concrete structures such as buildings, bridges, roads, tunnels, water conservancy projects, etc., and have good adaptability.
