EN S355J2 H-beam is a type of structural steel that has been highly regarded in various industries due to its exceptional properties. This article aims to provide a thorough overview of EN S355J2 H-beam, including its chemical composition, mechanical properties, heat treatment, dimension range, main applications, and relevant supply cases by TJC Steel.

 

Composition

EN S355J2 H-beam is made from alloyed steel, which contains the following chemical elements:

- Carbon (C): 0.20%

- Silicon (Si): 0.55%

- Manganese (Mn): 1.60%

- Phosphorus (P): 0.025%

- Sulfur (S): 0.025%

- Chromium (Cr): 0.30%

- Nickel (Ni): 0.50%

- Molybdenum (Mo): 0.10%

 

Mechanical Properties

EN S355J2 H-beam has excellent mechanical properties, as shown below:

- Yield strength: 355 MPa

- Tensile strength: 470-630 MPa

- Elongation: 22%

- Impact test temperature: -20℃

- Charpy V-notch impact value: 27J at -20℃

 

Heat Treatment

EN S355J2 H-beam is typically supplied in a normalized or controlled-rolled condition. Normalization is a heat treatment process that involves heating the steel to a temperature above its critical point, holding it at that temperature for a period, and then cooling it in still air. Controlled-rolling, on the other hand, involves rolling the steel at a controlled temperature and strain rate to achieve specific mechanical properties.

 

Dimension Range

EN S355J2 H-beam is available in various sizes, with the following dimensions:

- Height: 100-1000 mm

- Flange width: 50-300 mm

- Web thickness: 4.5-14.5 mm

- Flange thickness: 7-32 mm

- Length: 6-16 m

 

Main Applications

EN S355J2 H-beam is commonly used in the following applications:

- Construction of bridges, buildings, and offshore structures

- Manufacturing of cranes, excavators, and agricultural machinery

- Production of drilling rigs, mining equipment, and conveyor systems

- Fabrication of pressure vessels, boilers, and storage tanks
