S355JR S275JR HEB100x100x6x10 H beam construction
Model identification: HEB100, where "HEB" indicates a model series of European standard H-shaped steel, and "100" indicates that the height and width of the steel are both 100mm.
Dimensions: HEB100x100x6x10 The specific dimensions are 100mm in height, 100mm in width, 6mm in web thickness, 10mm in flange thickness, and weigh about 20.4 kg per meter.
S355JR h shaped steel Material characteristics
It belongs to the hot-rolled low-alloy high-strength structural steel in the European standard EN10025-2. The "S" in the grade indicates structural steel, "355" means that its minimum yield strength reaches 355MPa, and "JR" means that its impact energy meets the J-level requirements, and it can maintain high toughness and ductility when impacted, effectively avoiding fracture and breakage.
It has good plasticity and weldability, can adapt to various processing and welding requirements, and is widely used in various structural projects.
S275JR h section steel material features
It is engineering and structural steel, made of carbon structural steel and low alloy structural steel, and belongs to non-alloy structural steel plate. Its minimum yield strength is 275MPa.
The chemical composition is mainly composed of iron, carbon, manganese, silicon and other elements, with a low carbon content, which is conducive to improving the plasticity and toughness of steel. It has good tensile strength, yield strength and hardness, as well as good impact toughness and welding performance, excellent cold and hot processing performance, and is convenient for subsequent processing.
Mechanical properties
S355JR structural h beam material: tensile strength is between 420-550MPa, yield strength is between 250-360MPa, and section shrinkage is greater than 27%.
S275JR h beam material: Taking the plate as an example, in the hot-rolled state, when the thickness is 40-63mm, the yield strength ReH≥255MPa, the tensile strength Rm is 410-580MPa, the elongation A≥19%, and the longitudinal impact energy Aku≥27J at an impact temperature of 20°C.
Physical properties
High cross-sectional efficiency: The unique cross-sectional shape effectively improves its bearing capacity while saving materials.
Good stability: The shape is similar to the letter "H", with high rigidity and stability, and can withstand large loads.
Lightweight: Compared with solid steel, H-shaped steel has better lightweight characteristics, which can reduce the dead weight of the structure and reduce costs.
Application areas
Commonly used in beam and column components of large-scale construction projects, such as high-rise buildings, heavy industrial plants, etc., and are also widely used in main beams, piers and other parts in bridge construction, which can meet the requirements of high load and fatigue resistance.
