HEB120x120x6.5x11 S355J0 H Section Steel Beam

HEB120x120x6.5x11 h profile steel model and size
Model identification: HEB120 h shaped steel beam belongs to a model series of European standard H-shaped steel, "120" means that the height and width of the steel are both 120mm.

Dimensions: The specific dimensions are height 120mm, width 120mm, web thickness 6.5mm, flange thickness 11mm, and the weight per meter is about 26.7kg.

S355J0 h beam profile material characteristics
Chemical composition: The main chemical components include carbon (≤0.24%), silicon (≤0.55%), manganese (≤1.60%), phosphorus, sulfur, etc., and a small amount of alloying elements such as nickel, chromium, copper, etc. are also added. The precise ratio of these elements ensures the excellent performance of the steel.

Mechanical properties: yield strength ≥355MPa, tensile strength between 470-630MPa, elongation ≥22%. At 0°C, the impact energy Aku≥27J shows good low-temperature impact toughness and can maintain stable performance in cold environments.

Processing performance: It has good weldability and processability, can adapt to various welding processes such as arc welding and gas shielded welding, and can easily perform processing operations such as cutting and bending.

Comparison with other materials
Compared with S355JR, S355J0 has a higher impact toughness level. The impact test temperature of S355JR is 20°C, while that of S355J0 is 0°C, which is more suitable for low-temperature environments. Compared with S355J2, the impact energy absorption value of S355J2 at -20°C should reach 40J, and the impact toughness is better than S355J0, but the comprehensive performance of S355J0 can also meet many engineering scenarios that have certain requirements for low-temperature performance, and the cost may be relatively low.
