S355JR/S355J0 762x292x226 Universal Section Beam
Performance of S355JR/S355J0 h beam steel structure
Chemical composition: The chemical composition of S355JR and S355J0 is similar, C≤0.22%, Si≤0.55%, Mn≤1.60%, P≤0.025%, S≤0.025%; S355J0 structural steel h beam requires stricter control of phosphorus and sulfur content, so that it performs better in low temperature impact performance.
Mechanical properties: The yield strength of both is not less than 355MPa, the tensile strength is between 470-630MPa, and the elongation is ≥22%; S355J0 has an impact energy of not less than 27J at room temperature, and can also guarantee a certain impact toughness at -20℃, while S355JR generally only guarantees room temperature impact performance.
762x292x226 h shaped beam steel specifications
Dimensions: height is 762mm, flange width is 292mm, theoretical weight per meter is 226kg; this size of steel has a large load-bearing capacity and bending resistance, suitable for structures with large loads.
Section characteristics: with wide flanges and relatively thick webs, the cross-sectional shape is reasonable, which can effectively resist bending and shear forces, and provide good stability and strength support for the structure.
Production process of 762x292x226 h type steel beam
It is usually produced by hot rolling process. The steel billet is heated to a high temperature to make it in a plastic state, and then the steel billet is gradually rolled into the required UB steel cross-sectional shape and size through multiple rolling passes.
During the rolling process, the structural properties and dimensional accuracy of the steel are guaranteed by controlling parameters such as rolling temperature, speed and reduction.
