h section 356x406x677 S355JR/S355J0 steel column
Material characteristics
Chemical composition: The main chemical composition of S355JR h profile steel and S355J0 steel h profile is similar, with C content ≤0.22%, Si content ≤0.55%, Mn content ≤1.60%, P content ≤0.025%, and S content ≤0.025%. A small amount of alloying elements such as chromium, nickel, and copper can help improve the corrosion resistance and fatigue resistance of steel.
The carbon content of S355JR h type beam is slightly higher than that of S355J0, while the upper limit of nitrogen content of S355J0 is higher than that of S355JR.
Mechanical properties: The yield strength of both is 355MPa, the tensile strength is between 470-630MPa, and the elongation is 22%. However, there are differences in impact toughness. S355JR requires an impact energy of 27J at 20℃, while S355J0 requires an impact energy of 27J at 0℃. S355J0 is more suitable for use in low temperature environments, while S355JR has better impact resistance at room temperature and higher temperatures.
