HRB400 rebar refers to hot-rolled ribbed steel bars with a yield strength of 400MPa, and its grade is HRB400. It is a low-carbon alloy steel with good plasticity, weldability and corrosion resistance. It is widely used in construction projects such as houses, bridges, roads and so on.
High strength: The yield strength is 400MPa, the tensile strength is 570MPa, and the elongation is 14%, which can improve the load-bearing capacity of the building.Good plasticity: HRB400 steel bars have good plasticity and can undergo large deformation without breaking when stressed, thereby improving the seismic performance of the building.Good weldability: HRB400 steel bars have good weldability and can be welded easily, thereby improving construction efficiency.Good corrosion resistance: HRB400 steel bars have a dense oxide film on the surface, which can effectively prevent corrosion and extend the service life of the building.Simple production process: The production process of HRB400 steel bars is relatively simple, the cost is low, and it is suitable for large-scale production.| Chemical composition | content (%) |
