EN 10025 S355 Steel
S355 steel is a European standard structural steel grade according to EN 10025-2:2004, offering superior properties compared to S235 and S275 steel in yield strength and tensile strength.
S355 Steel Quality Grades
- S355JR (1.0045)
- S355J0 (1.0553)
- S355J2 (1.0577)
- S355K2 (1.0596)
Steel Grade Designation Meaning
- "S": Structural steel
- "355": Minimum yield strength value for flat and long steel thickness ≤ 16mm
- "JR": Impact energy value minimum 27 J at room temperature (20°C)
- "J0": Withstands impact energy at least 27 J at 0°C
- "J2": Minimum impact energy value 27 J at -20°C
- "K2": Minimum impact energy value 40 J at -20°C
