Steel S355J2 (Material 1.0577)
S355J2 steel (1.0577) is a quality grade of S355 steel, which is one of the commonly used non-alloy structural steels in Europe. According to EN 10025-2: Hot-rolled structural steel products, S355 steel is divided into 4 quality grades, namely:
- S355JR (1.0045),
- S355J0 (1.0553),
- S355J2 (1.0577), previous names: S355J2G3 and S355J2G4 in EN 10025:1990,
- S355K2 (1.0596), previous names: S355K2G3 and S355K2G4 in EN 10025:1990.
EN 10025 S355J2 equivalent ASTM A992/A992M; Australian AS/NZS 3678: Grade 350 L20; Canadian G40.20/G40.21: 350WT (55WT); Chinese GB/T 1591: Q355D; and Indian standard IS 2062: E350.
EN 10025 S355J2 Meaning
S355J2 Meaning: “S” means “Structural Steel”; 355 indicates that the material has a minimum yield strength of 355 MPa when the nominal thickness is ≤ 16mm; and “J2” indicates that the material has a minimum impact energy of 27J at -20°C (-4°F).
