Manganese (Mn): ≤1.60%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%
Mechanical properties
Yield strength: about 355 MPa
Tensile strength: 470-630 MPa
Elongation: ≥21%
Characteristics: easy to weld and process; good impact resistance at room temperature.
Uses: Widely used in building structures (such as beams, columns, trusses), bridges, mechanical equipment manufacturing, etc.
S355J0 h section beam material
Material introduction: S355J0 is one of the S355 series, similar to S355JR, but with higher impact performance requirements.
Chemical composition
Carbon (C): ≤0.22%
Silicon (Si): ≤0.55%
Manganese (Mn): ≤1.60%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%
Mechanical properties
Yield strength: about 355 MPa
Tensile strength: 470-630 MPa
Impact temperature: 0℃
Characteristic impact performance is better than S355JR; also has good welding performance.
Uses: Suitable for building structures, bridge engineering and mechanical equipment manufacturing in low temperature environments.
UB steel comparison
Design features: UB h beam structure is a kind of British standard H-shaped steel, with parallel flange I-shaped cross section; manufactured by hot rolling process, with high strength and stability.
Structural advantages: easy to connect with other structural materials, widely used in high-rise buildings and large bridges, can effectively improve the overall stability and bearing capacity of the structure.
UB 406x140x39 h shaped steel
Section height: 406 mm
Web width: 140 mm
Average thickness: 39 mm
Material: Usually S355J0 or S355JR.
Weight: about 39 kg/m.
Use: used for beams, columns and trusses in building structures; suitable for load-bearing components with large loads.
UB 406x140x46 h section steel
Section height: 406 mm
Web width: 140 mm
Average thickness: 46 mm
Material: Usually S355J0 or S355JR.
Weight: about 46 kg/m.
Application: Also suitable for beams, columns and trusses in building structures; due to the thicker cross-section, its bearing capacity is stronger than UB 406x140x39 steel h beam, and it is suitable for scenes with higher strength requirements.
