S355J0 S355JR UB 457*152*82 structural steel beam
S355J0 h section steel beam
Chemical composition: carbon (C) content ≤ 0.22%, silicon (Si) content ≤ 0.55%, manganese (Mn) content ≤ 1.60%, phosphorus (P) content ≤ 0.025%, sulfur (S) content ≤ 0.025%.
S355J0 h shaped beam requires good impact toughness at 0℃, and has higher requirements for the purity and organizational structure of steel. Some trace elements may be added to ensure its low temperature performance.
Mechanical properties: yield strength ≥ 355MPa, tensile strength between 450 - 680MPa, elongation between 17% - 22%. At 0℃, the longitudinal impact energy is not less than 27J, which can maintain good strength and toughness in low temperature environment and effectively prevent material embrittlement or fracture.
S355JR h-shaped iron beam
Chemical composition: carbon (C) content ≤ 0.22%, silicon (Si) content ≤ 0.55%, manganese (Mn) content ≤ 1.60%, phosphorus (P) content ≤ 0.025%, sulfur (S) content ≤ 0.025%.
Mechanical properties: The yield strength varies according to the thickness of the steel plate. When the thickness is ≤ 16mm, the yield strength is ≥ 355MPa; when the thickness is 16-40mm, the yield strength is ≥ 345MPa. The tensile strength is generally between 470-630MPa.
At + 20℃, the longitudinal impact energy is not less than 27J. It has good plasticity and room temperature impact toughness, is easy to process, can absorb energy through plastic deformation when subjected to external force, and improve structural safety.
UB 457x152x82 Steel Beam Specifications
Dimensional parameters: UB stands for universal beam steel, 457x152x82 universal beam represents the specifications of the steel, where 457mm is the height of the steel, 152mm is the width of the flange, and 82kg/m is the weight of the steel per meter.
Sectional characteristics: With narrower flanges and wider webs, this cross-sectional shape makes it perform better in bending and shear resistance, can effectively share the load, and enhance the strength and stability of the overall structure.
