What is the ASTM equivalent of S355J2 steel?

Gangsteel, a leading manufacturer and exporter of structural steel plates, supplies premium EN 10025-2 S355J2 steel plates for construction, bridges, and heavy machinery applications. The ASTM equivalent of S355J2 steel is A572 Grade 50, a high-strength low-alloy steel with similar strength and low-temperature toughness for load-bearing structures. This article explores the ASTM equivalent of S355J2 steel, detailing its equivalents, chemical compositions, mechanical properties, and applications, helping engineers and fabricators select suitable alternatives for US projects.

astm equivalent of s355j2 steel Overview of S355J2 Steel

S355J2 steel is a European standard grade for hot-rolled structural steels with a minimum yield strength of 355 MPa and impact at -20°C. Its ASTM equivalent is A572 Grade 50, used for similar applications in the US. Gangsteel offers S355J2 with ASTM equivalents like EN 10025-2 S355K2 steel and EN 10025-2 S450J0 steel, ensuring compliance for global projects.

astm equivalent of s355j2 steel Grade Mapping

S355J2 has direct equivalents in ASTM standards. The table below maps it to key ASTM grades:

Key Notes on Grade Mapping:

• ASTM A572 Gr 50: Primary equivalent, with yield 345 MPa and similar impact.
• Substitution is common in US projects for European specs.

Gangsteel provides dual-certified plates, including EN 10025-2 S235J2 steel and EN 10025-2 S355JR+N.

astm equivalent of s355j2 steel Chemical Composition Comparison

Chemical compositions are similar, with low carbon for weldability. The table below compares S355J2 with ASTM A572 Gr 50 (% by weight, max values):

Key Notes on Chemical Composition:

• S355J2 has stricter P/S for toughness.
• ASTM A572 Gr 50 has broader limits but comparable weldability.

Gangsteel’s plates meet multiple standards for easy equivalence.

astm equivalent of s355j2 steel Mechanical Properties Comparison

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

Key Notes on Mechanical Properties:

• Both have similar strength, but EN 10025-2 guarantees impact.
• ASTM A572 Gr 50 is versatile but may need testing for cold use.

Gangsteel provides tested plates for reliable performance.

astm equivalent of s355j2 steel Applications and Substitution Considerations

S355J2 is used in construction (bridges), offshore (platforms), and machinery (cranes). Its ASTM equivalent A572 Gr 50 substitutes for:

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

Substitution considerations:

• Standards Compliance: EN for Europe, ASTM for US.
• Toughness: EN has impact testing; ASTM may not.
• Cost/Availability: ASTM in US, EN in Europe; Gangsteel bridges this.

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