EN 10025-2 S355JR Hot Rolled Structural H Steel Beam
S355JR hot-rolled H-beam is a non-alloy steel specially designed for structural applications that require higher strength and good weldability. The "JR" suffix indicates the minimum impact energy value of the material at room temperature.
The chemical composition of S355JR hot rolled structural H-beams typically includes
Carbon (C): up to 0.22%
Manganese (Mn): up to 1.60%
Silicon (Si): up to 0.55%
Phosphorus (P): up to 0.045%
Sulphur (S): up to 0.045%
S355JR H-beams have the following mechanical properties
Yield strength: min. 355 MPa
Tensile strength: 510-630 MPa
Elongation: min. 22% (thickness <= 16mm)
Impact energy: 27 J at -20°C (JR condition)

S355JR hot rolled H-beams are used in a variety of applications including: building and bridge construction; industrial sheds and warehouses; heavy machinery support structures; crane booms; marine and offshore structures; highway structures, etc.
The production of S355JR H-beam involves the following steps:
Hot rolling: The steel is heated above its recrystallization temperature and then rolled into the desired shape.
Cooling: The steel beam is cooled to room temperature, which helps achieve the desired mechanical properties.
