Structural Beam S355JR Hot-Rolled Steel H Beam
S355JR structural H-beam is a low-alloy high-strength structural steel that complies with the European standard EN 10025, which is equivalent to Q345B in the Chinese standard. Among them, "S" stands for structural steel, "355" means the minimum yield strength is 355MPa, and "JR" stands for the quality grade, indicating that it has certain impact resistance at room temperature.
The main chemical composition limits of S355JR H-beam columns are C≤0.22%, Si≤0.55%, Mn≤1.60%, P≤0.025%, S≤0.025%. Small amounts of other alloying elements can also be added to improve the performance of the steel.
GNEE is available in a variety of sizes, such as HEA (European wide flange H-beam), HEB (European standard size H-beam) and HEM (European narrow flange H-beam). Common sizes include HE100A (100×96×5×8), HE120B (120×120×6.5×11), etc.
Performance characteristics of S355JR H-beam
Mechanical properties: high strength, minimum yield strength of 355MPa, tensile strength of 470-630MPa.
Processability: good formability, easy to cut, bend and drill.
Weldability: excellent weldability, can be welded by a variety of welding methods.
Corrosion resistance: alloy elements are added, corrosion resistance is better.
Hot rolling process: The production of S355JR hot-rolled H-beam usually requires heating the billet to a high temperature and then passing through a series of rolling mills to form the required H-section.
Quality control: During the production process, we will implement strict quality control measures, including chemical composition analysis, mechanical property testing and non-destructive testing to ensure that the products meet relevant standards and customer requirements.
