Hot-rolled S355JR S355J0 UB 254*102*22 Universal Beam
UB 254*102*22 h section beam can give full play to the mechanical properties of the material when subjected to bending and shear forces, effectively improving the bearing capacity and stability of the structure.
Chemical composition: S355JR h beam structure and S355J0 h shaped steel are both low-carbon alloy structural steels with similar main chemical compositions, and a small amount of alloying elements are added to help improve the strength, toughness and corrosion resistance of the steel.
The carbon content of S355J0 is slightly higher than that of S355JR, while the upper limit of nitrogen content of S355J0 is higher than that of S355JR.
Mechanical properties: The yield strength is 355MPa, the tensile strength is between 470-630MPa, and the elongation is 22%. The impact energy required for S355JR steel h beam at 20℃ is 27J, while the impact energy required for S355J0 h beam at 0℃ is 27J.
High strength: The yield strength reaches 355MPa, which can withstand large loads and meet the requirements of engineering structures such as buildings and bridges for bearing capacity.
Good weldability: UB 254*102*22 h beam steel structure has good welding performance and is easy to weld and form.
Excellent processing performance: UB 254*102*22 h section steel is easy to cut, drill, cold bend and other processing operations.
