914x305x201 S355JR/S355J0 Structural Hot Rolled Beam
S355JR structural h beam
S355JR steel h column is a low-alloy high-strength structural steel that meets the European standard EN10025, which is equivalent to Q345B steel in China.
The carbon content of S355JR h section beam is ≤0.22%, the silicon content is ≤0.55%, the manganese content is ≤1.60%, and the phosphorus and sulfur contents are both ≤0.025%. The content of these elements ensures the strength and toughness of the steel, and also has a certain impact on the welding performance.
S355JR h beam structure has high yield strength and tensile strength, with a minimum yield strength of up to 355MPa, an actual yield strength between 300-400MPa, a tensile strength between 470-630MPa, an impact toughness of 27J at 20°C, and good corrosion resistance in general atmospheric environments.
S355J0 steel h beam
S355J0 h section steel is a low alloy high strength structural steel under the European standard EN10025.
The yield strength of S355J0 is 355MPa, the tensile strength is between 470-630MPa, and the elongation reaches 22%.
The main chemical components of S355J0 h shaped steel include carbon, silicon, manganese, phosphorus, sulfur, and a small amount of alloying elements such as chromium, nickel, copper, etc. The carbon content is generally between 0.12% and 0.22%, the silicon content is between 0.35% and 1.0%, the manganese content is between 1.00% and 2.1%, and the phosphorus and sulfur contents are usually controlled below 0.025%.
Compared with S355JR, the impact test temperature of S355J0 is 0℃, while S355JR is generally tested at 20℃.
Specifications of UB 914x305x201 h beam
UB indicates a type of British standard H-beam, 914 indicates that the height of the steel is 914mm, 305 indicates that the flange width is 305mm, and 201 indicates that the theoretical weight per meter is 201kg.
Performance characteristics
High strength: S355JR and S355J0 have high yield strength and tensile strength, which enables UB 914x305x201 steel to withstand large loads and stresses, and is suitable for structures that bear heavy loads.
