Hot-rolled S355J0 UB457*152*67 457*152*74 Universal Beam

Compared with S355JR h-shaped steel beam, the main difference of S355J0 steel beam is that its impact test temperature requirement is lower. When the Charpy V-notch impact test is carried out at 0°C, the impact energy absorption value should not be less than 27J, which is more suitable for applications in low temperature environments.

UB 457x152x67 457x152x74 universal beam
Dimensions: The width and height of the two models are the same, 152 mm and 457 mm respectively, the difference is the weight per meter, 67 kg/m and 74 kg/m respectively. UB 457x152x74 is thicker and heavier, with higher strength and load-bearing capacity.

Chemical composition of S355J0 structural steel beam: carbon content does not exceed 0.22%, silicon does not exceed 0.55%, manganese does not exceed 1.60%, and phosphorus and sulfur contents are controlled below 0.035% respectively. The proportions of these elements ensure that the steel has good weldability and mechanical properties.

Mechanical properties of S355J0 h type beam: yield strength (ReH) ≥ 355 MPa; tensile strength (Rm) between 470 - 630 MPa; impact energy (KV2) at 0°C ≥ 27 J.

UB type steel made of S355J0 is used in building structures that require high strength and cold resistance, such as bridge construction, high-rise building frames, etc., due to its excellent mechanical properties, especially its good adaptability to low temperature conditions. In addition, this type of steel is also suitable for various complex welded structures due to its good welding performance.
