S355JR material h beam features
Chemical composition: As a low-alloy high-strength structural steel, in addition to the basic elements such as carbon, silicon, manganese, phosphorus, sulfur, etc., it also contains a small amount of alloying elements such as niobium, vanadium, titanium, etc. The addition of these elements improves the strength and toughness of the steel.

Mechanical properties: The yield strength is 355MPa, the tensile strength is between 470-630MPa, and the impact energy is not less than 27J at 20℃. Its strength is significantly higher than that of S275JR, and it has good toughness, cold working performance and welding performance.
Processing performance: It can adapt to a variety of welding processes, such as arc welding, gas shielded welding, etc., and performs well in both cold and hot working, and can meet the processing requirements of complex shape components.

Physical properties
Both materials of HEB180 steel have good bending resistance due to the H-section. The flange is wide and thick, the web is thin and long, and the connection between the flange and the web adopts a rounded transition, which can improve the overall stability and stress dispersion ability of the steel and enhance the overall bearing capacity.
