S355J0 254x146x31 254x146x37 h section beam
The section height of 254x146x31 h beam profile and 254x146x37 h profile steel are both 254 mm and 146 mm wide, but their weight per meter is different, 31 kg and 37 kg respectively. The 37 kg/m steel is heavier than the 31 kg/m steel and has thicker or larger web and flange thickness.
Chemical composition of S355J0 steel beam h: carbon C≤0.22%, silicon Si≤0.55%, manganese Mn≤1.60%, phosphorus P≤0.025%, sulfur S≤0.025%, and other alloying elements such as nickel Ni, chromium Cr, copper Cu, molybdenum Mo, etc.
Mechanical properties of S355J0 material h beam
Yield strength: ≥355MPa
Tensile strength: 470-630MPa
Elongation: ≥22%
Impact toughness: impact energy ≥27J at 0℃, some standards require impact energy ≥27J at -20℃
Application areas of S355J0 h type steel beam
Buildings and bridges: suitable for structures that require high loads and seismic resistance, such as high-rise buildings, gymnasiums, and large highway/railway bridges.
Machinery manufacturing: used for heavy-duty parts such as heavy machinery and lifting equipment.
Ships and automobiles: can be used for hull structures, offshore platforms and lightweight automotive parts, especially in corrosive environments.
Processing performance of S355J0 h type beam
1. It has good weldability and processability, and is suitable for various welding methods such as arc welding and gas shielded welding.
2. When cold forming or hot forming, attention should be paid to the ductility of the material and the possible risk of cold cracking.
