HRBF400 steel bar is a fine-grained hot-rolled steel bar with a grade of HRBF400, which means hot-rolled ribbed, ultra-fine-grained seismic steel bar with a yield strength of 400MPa. This steel bar is formed by controlled rolling and controlled cooling. Its metallographic structure is mainly ferrite plus pearlite. There must be no other structures that affect the performance. The grain size is not coarser than grade 9.

CHARACTERISTICS

HRBF400 steel bar has an ultra-fine grain structure, which can greatly improve the performance of steel without increasing the alloy content. This process significantly improves the strength and toughness of steel, and is suitable for projects with high requirements for strength and seismic performance.

USES

HRBF400 steel bar is widely used in civil engineering projects such as houses, bridges, and roads, especially in structures that require high strength and good seismic performance. Due to its excellent mechanical properties, HRBF400 steel bar can reduce the use of steel, thereby reducing project costs.
