HEA180 S355NL S355ML wide flange h beam

HEA180 steel beam is a hot rolled H-beam that meets European standards and is commonly used in building structures and other applications that require high strength and good weldability. When made of S355NL or S355ML, it is particularly suitable for applications that require low temperature impact performance.

S355NL h beam material characteristics
Definition: S355NL is a low alloy high strength structural steel produced according to EN 10025-3 standard. "N" indicates normalized or normalized rolled state, and "L" indicates that it has specific low temperature impact properties (minimum impact energy at -50°C).
Yield strength (ReH): minimum value is 355 MPa
Tensile strength (Rm): 470-630 MPa
Elongation after fracture (A): varies according to the thickness of the specimen, but usually not less than 20%
Impact energy (KV2): at least 27J for longitudinal specimens at -50°C
Applicable scenarios: Suitable for cold areas or applications that require high toughness under low temperature conditions, such as bridge construction, high-rise buildings, etc.

S355ML steel h beam characteristics
Definition: S355ML is also a low alloy high strength structural steel, but produced according to EN 10025-4 standard. "M" indicates improved low temperature toughness steel, delivered in normalized or normalized rolled state.
Yield strength (ReH): also minimum value of 355 MPa
Tensile strength (Rm): 470-630 MPa
Elongation after fracture (A): varies according to the thickness of the specimen, usually not less than 20%
Impact energy (KV2): Compared with S355NL, S355ML may have better impact performance at lower temperatures, the specific value depends on the technical specifications provided by the manufacturer.
Applicable scenarios: Suitable for use in extreme low temperature environments, such as infrastructure construction in the Arctic or other engineering projects under extremely cold conditions.

Application of HEA180 h section steel
Construction industry: used in frame structures, bridge construction and other situations where the influence of low temperature needs to be considered.
Industrial facilities: suitable for heavy equipment support structures in manufacturing plants, especially in cold areas.
Other areas: including but not limited to the construction of public facilities such as railway tracks, highway bridges, etc.
