What is the EN 10025 S355J2G3 equivalent to?

Gangsteel, a leading manufacturer and exporter of structural steel plates, supplies premium EN 10025 S355J2G3 equivalent materials for construction, bridges, and heavy machinery applications. EN 10025 S355J2G3 is an older non-alloy structural steel grade equivalent to S355J2+N in the updated EN 10025-2, offering high strength and low-temperature toughness. This article explores what EN 10025 S355J2G3 is equivalent to, detailing its equivalents, chemical compositions, mechanical properties, and applications, helping engineers and fabricators select suitable alternatives for legacy projects.

en 10025 s355j2g3 equivalent Overview of S355J2G3

S355J2G3 is from the old EN 10025 standard, equivalent to S355J2+N in EN 10025-2, with normalized condition for improved toughness. Its equivalents include ASTM A572 Grade 50 (USA) and GB Q355D (China). Gangsteel offers S355J2G3 equivalents with modern certification, including EN 10025-2 S355J0 and EN 10025-2 S235J0, ensuring compliance for global projects.

en 10025 s355j2g3 equivalent Grade Mapping

S355J2G3 has direct equivalents in other standards. The table below maps it to key grades:

Key Notes on Grade Mapping:

• EN 10025-2 S355J2+N: Direct modern equivalent, with +N for normalization.
• ASTM A572 Gr 50: Functional for general use, with similar yield.
• DIN ST52-3N: Match for European projects.
•  

Gangsteel provides dual-certified plates, including EN 10025-2 S275JR and EN 10025-2 S275J0 steel.

en 10025 s355j2g3 equivalent Chemical Composition Comparison

Chemical compositions are similar, with low carbon for weldability. The table below compares S355J2G3 with EN 10025-2 S355J2+N and ASTM A572 Gr 50 (% by weight, max values):

Key Notes on Chemical Composition:

• S355J2G3 and S355J2+N are nearly identical, with minor P/S adjustments in the new standard.
• ASTM A572 Gr 50 has broader limits but comparable weldability.

Gangsteel’s plates meet multiple standards for easy equivalence.

en 10025 s355j2g3 equivalent Mechanical Properties Comparison

Mechanical properties are close, with S355J2G3 offering specified impact at -20°C. The table below compares S355J2G3 with EN 10025-2 S355J2+N and ASTM A572 Gr 50 (for plates up to 16 mm):

Key Notes on Mechanical Properties:

• S355J2G3 and S355J2+N are equivalent, with minor tensile adjustments.
• ASTM A572 Gr 50 has similar strength but no mandatory impact.

Gangsteel provides tested plates for reliable performance.

en 10025 s355j2g3 equivalent Applications and Substitution Considerations

S355J2G3 is used in construction (bridges), offshore (platforms), and machinery (cranes). Its equivalent S355J2+N substitutes for:

• High-rise buildings and heavy bridges.
• Wind turbines and moderate-cold machinery.

Substitution considerations:

• Standards Compliance: Old EN for legacy, new EN for current projects.
• Toughness: Both have impact at -20°C.
• Cost/Availability: S355J2+N is more common; Gangsteel bridges this.

For low-temperature, check EN 10025-2 S355J2 steel or EN 10025-2 S355K2 steel.
