S355J0 203x203x86 Universal Steel Section Column
Material characteristics of S355J0 h-shaped iron beam
S355J0 h-section steel is a low-alloy high-strength structural steel under the European standard EN 10025, with a carbon (C) content of ≤0.20%, a silicon (Si) content of ≤0.55%, a manganese (Mn) content of ≤1.60%, a phosphorus (P) content of ≤0.040%, a sulfur (S) content of ≤0.040%, and a small amount of alloying elements such as chromium (Cr), nickel (Ni), and copper (Cu). It has good corrosion resistance and fatigue resistance.
Mechanical properties of S355J0 h-profile steel
Strength: The yield strength is 355MPa, and the tensile strength is between 470 and 630MPa. It has high strength and can withstand large loads.
Toughness: The impact energy test temperature is 0℃, and it can still maintain good impact toughness at 0℃. Compared with some steels with normal temperature impact, it is more suitable for use in low temperature environment.
Ductility: Elongation ≥22%, with excellent ductility.
Processing and welding performance of S355J0 steel beam h
Processing performance: easy to cut, bend and form, convenient for various processing operations, and can meet the processing needs of different projects.
Welding performance: Good welding performance, suitable for a variety of welding processes, only need to control the process parameters during welding, can ensure the welding quality, and obtain reliable welding joints.
Implementation standard: European standard is EN 10025-2, corresponding to the grade Q355C in the Chinese standard GB/T 1591.
