HRB400/HRB400E Steel Wire Rod

HRB400 is manufactured using a meticulous hot rolling process, which involves heating and rolling steel bars to achieve optimal performance characteristics. This innovative production method not only increases the material’s strength, it also ensures exceptional ductility, allowing it to withstand significant stress and deformation without compromising its structural integrity. The “HR” in HRB400 stands for “hot rolled,” a testament to the advanced technology used in its manufacturing process.What really sets HRB400 apart is its amazing 400 megapascal (MPa) yield strength, which significantly exceeds that of ordinary carbon steel. This high yield strength means enhanced load-bearing capacity, making HRB400 ideal for a wide range of applications, from high-rise buildings to bridges and infrastructure projects. Engineers and architects can count on HRB400 to provide the reliability and durability they need for their most ambitious designs.

1. High strength: The yield strength of HRB400 steel bars is 400 MPa, which has higher strength and tensile properties compared to general carbon steel, and can effectively increase the bearing capacity of concrete components.

2. Good plasticity: HRB400 steel bars have good toughness and elongation after being subjected to stress, and can maintain high strength even if bending and deformation occur.

3. Good welding performance: HRB400 steel bars have good weldability and can be welded with other steels, making them convenient for use in construction.

4. Weather resistance: HRB400 steel bars have good weather resistance and can be used for a long time in harsh weather conditions, making them less susceptible to oxidation and corrosion.

5. Simple construction: The shape of HRB400 steel bars is relatively simple, usually flat or circular, which is convenient for processing and use.
