914x419x446 914x419x488 S355JR Universal Beam
S355JR structural steel beam is a low-alloy high-strength structural steel that meets the European standard EN 10025-2. Its chemical composition is carbon (C) ≤ 0.22%, silicon (Si) ≤ 0.55%, manganese (Mn) ≤ 1.60%, phosphorus (P) ≤ 0.025%, and sulfur (S) ≤ 0.025%.
S355JR material h beam has good comprehensive properties by adding a small amount of alloy elements. The yield strength is not less than 355MPa, the tensile strength is between 470-630MPa, and the elongation after fracture is not less than 22%.
Compared with S355J0 steel beam h, the impact test temperature of S355JR h beam material is 20℃. It has good impact toughness at room temperature and can withstand a certain degree of impact and vibration loads.
H-beam specification comparison
914x419x446 h beam section: indicates that the height of the profile is 914mm, the flange width is 419mm, and the theoretical weight per meter is 446kg.
914x419x488 h profile steel: The height of the profile is 914mm, the flange width is 419mm, and the theoretical weight per meter is 488kg.
Performance characteristics of Universal Structural Steel Beam
High strength: Due to the high strength characteristics of S355JR material, these two types of steel can withstand large loads and are suitable for occasions with high requirements for structural strength, such as load-bearing structures of large buildings, support frames of heavy machinery, etc.
Good toughness: It has good impact toughness at room temperature (20℃), and can absorb a certain amount of energy without brittle fracture when subjected to impact or vibration, thereby improving the safety and reliability of the structure.
Easy processing: It has good processing performance and can be made into components of various shapes and sizes through cutting, welding, bending and other processing methods to meet the needs of different engineering designs. Moreover, during the processing, the performance of the steel will not be greatly affected, and the quality of the processed components can be guaranteed.
Good corrosion resistance: In the general atmospheric environment, it has good corrosion resistance, can resist a certain degree of oxidation and corrosion, and extend the service life of the structure.
