S355JR steel h beam characteristics
Chemical composition: mainly contains iron (Fe), and contains alloy elements such as carbon (C), manganese (Mn), silicon (Si), etc. The specific content must comply with EN 10025-2 standard.

Mechanical properties
Yield strength (ReH) ≥ 355 MPa
Tensile strength (Rm) between 470 and 630 MPa
Elongation after fracture (A) ≥ 21%
Impact absorption energy KV2 (20°C) ≥ 27 J
Applicable temperature: suitable for use in normal temperature environment.

S355J0 h section steel Features
Chemical composition: Similar to S355JR, but may be slightly adjusted to meet specific requirements in order to achieve better low temperature toughness.

Mechanical properties
Yield strength (ReH) ≥ 355 MPa
Tensile strength (Rm) between 470 and 630 MPa
Elongation after fracture (A) ≥ 21%
Impact absorption energy KV2 (0°C) ≥ 27 J

Applicable temperature: Specially designed for applications at lower temperatures, as low as 0°C, ensuring good toughness and reliability of the material under such conditions.

Application areas
S355JR h shaped steel: Widely used in construction, bridges, machinery manufacturing and other fields, especially in those applications that have high requirements for material strength but do not involve extreme low temperatures.

S355J0 h beam structure: Due to its good low temperature toughness, it is suitable for structural parts that need to be used in cold environments, such as building frames, bridges and other infrastructure projects in northern regions.
