HEA360 HEB360 S355NL/S355ML Wide Flange Beam

S355NL S355ML structural h beam can be used to manufacture HEA (European standard wide flange I-beam) and HEB (European standard narrow flange I-beam) sections, such as HEA360 and HEB360.

S355NL structural steel h beam material properties: This is a normalized or normalized rolled low-alloy high-strength structural steel with good low-temperature toughness and is suitable for use in an environment of -50°C.

S355ML h metal beam material properties: This steel is made by thermomechanical rolling (TMCP) or controlled rolling, and is also suitable for low-temperature environments, but its yield strength decreases with increasing material thickness.

For H-beams of HEA360 and HEB360 h beam materials, they can be made of different materials (such as S355NL or S355ML), but the main dimensional parameters of these models are usually the same.

S355NL and S355ML h beam steel structures have different production processes, and their mechanical properties will be different. For example, S355NL h section steel beam has higher impact toughness requirements at low temperatures.

The choice of S355NL or S355ML in the application scenario depends on the specific engineering requirements, such as whether higher low temperature toughness or specific yield strength is required.
