What is the ASTM material equivalent to S355JR?

Gangsteel, a leading manufacturer and exporter of structural steel plates, supplies premium EN 10025-2 S355JR steel plates for construction, bridges, and heavy machinery applications. The ASTM material equivalent to S355JR is A572 Grade 50, a high-strength low-alloy steel with similar yield strength for load-bearing structures. This article explores the ASTM material equivalent to S355JR, detailing its equivalents, chemical compositions, mechanical properties, and applications, helping engineers and fabricators select suitable alternatives for US projects.

astm material equivalent to s355jr Overview of S355JR

S355JR 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 S355JR with ASTM equivalents like EN 10025-2 S355J0 and EN 10025-2 S235J0, ensuring compliance for global projects.

S355JR 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 for high-strength use.
• Substitution is common in US projects for European specs.

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

astm material equivalent to s355jr Chemical Composition Comparison

Chemical compositions are similar, with low carbon for weldability. The table below compares S355JR with ASTM A572 Gr 50 (% by weight, max values):

Key Notes on Chemical Composition:

• EN 10025-2 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 material equivalent to s355jr Mechanical Properties Comparison

Mechanical properties are close, with EN 10025-2 offering specified impact. The table below compares S355JR 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 material equivalent to s355jr Applications and Substitution Considerations

S355JR 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.
