S355J0 h-shaped iron beam: carbon (C) content does not exceed 0.24%, silicon (Si) content does not exceed 0.60%, manganese (Mn) content does not exceed 1.70%, phosphorus (P) and sulfur (S) content do not exceed 0.040%, copper (Cu) content does not exceed 0.60%, nitrogen (N) content does not exceed 0.014%.
Mechanical properties comparison
S355JR h-profile steel: yield strength is 355MPa, tensile strength is between 450-680MPa, and elongation is 22%. JR represents the impact energy of 27 joules at 20℃.
S355J0 h-shaped metal: yield strength is 355MPa, tensile strength is between 450-680MPa, and elongation is 22%. J0 means that its impact toughness level is 0℃, and an impact toughness test at 0℃ is required. Its impact toughness at low temperature is better than that of S355JR.
UB 686x254x125 hot rolled h beam specifications
Cross-section size: height is 686mm, flange width is 254mm, and weight per meter is about 125kg.
Cross-section characteristics: It has wide wing plates and thick webs, and the cross-section shape is H-shaped. This shape makes the steel have excellent strength and rigidity, and can effectively resist and disperse the effects of various forces, providing guarantee for the stability of the structure.
