What is EN 10025 steel equivalent to?

Gangsteel, a leading manufacturer and exporter of structural steel plates, supplies premium EN 10025 steel and equivalents for construction, bridges, and heavy machinery applications. EN 10025 is a European standard series for structural steels, and its materials have equivalents in other international standards like ASTM, DIN, JIS, and GB. This article explores what EN 10025 steel is equivalent to, detailing equivalents by part of the standard, chemical compositions, mechanical properties, and applications, helping engineers and fabricators select suitable alternatives for global projects.

en 10025 steel equivalent Overview of EN 10025 Standard

EN 10025 is a family of European standards (published by CEN) for hot-rolled structural steels, divided into 6 parts covering non-alloy, fine grain, weathering, and high-strength steels. It ensures consistent quality for welded, bolted, and riveted structures. Equivalents vary by part:

• EN 10025-2 (non-alloy): ASTM A36 (S275JR), A572 Gr 50 (S355JR).
• EN 10025-3 (fine grain): ASTM A709 Gr 50W.
• EN 10025-5 (weathering): ASTM A588.
• EN 10025-6 (high-strength): ASTM A514.

Gangsteel offers EN 10025 steel with equivalents like EN 10025-2 S355J0 and EN 10025-2 S235J0, ensuring CE marking compliance.

en 10025 steel equivalent Grade Mapping by Part

EN 10025 equivalents are mapped by part and grade. The table below shows key mappings:

Key Notes on Grade Mapping:

• EN 10025-2 (non-alloy): Equivalents like ASTM A36 for S275JR are common for general construction.
• EN 10025-3 (fine grain): ASTM A709 Gr 50W for weathering variants.
• EN 10025-5 (weathering): ASTM A588 for corrosion-resistant structures.
• EN 10025-6 (high-strength): ASTM A514 for quenched and tempered steels.

These mappings are functional, but verify for specific codes. Gangsteel provides dual-certified plates, including EN 10025-2 S275JR and EN 10025-2 S275J0 steel.

en 10025 steel equivalent Chemical Composition Comparison

Chemical compositions are similar, with low carbon for weldability. The table below compares EN 10025-2 S355JR (representative) with equivalents (% by weight, max values):

Key Notes on Chemical Composition:

• EN 10025-2 materials have stricter P/S for toughness, similar to DIN and JIS equivalents.
• ASTM A572 Gr 50 has broader limits but comparable weldability.
• GB Q345B has higher Mn for strength, making it a close match for S355JR.

Gangsteel’s plates meet multiple standards for easy equivalence.

en 10025 steel equivalent Mechanical Properties Comparison

Mechanical properties are close, with EN 10025-2 offering specified impact toughness. The table below compares EN 10025-2 S355JR with equivalents (for plates up to 16 mm):

Key Notes on Mechanical Properties:

• EN 10025-2 guarantees impact toughness, superior for brittle fracture resistance.
• ASTM A572 Gr 50 has similar strength but no mandatory impact test.
• DIN ST52-3 and GB Q345B match closely, with JIS SM490A slightly lower yield for thinner plates.

Gangsteel provides tested plates for reliable performance.

en 10025 steel equivalent Applications and Substitution Considerations

EN 10025 steel is used in construction (buildings, bridges), offshore (platforms), and machinery (cranes). Equivalents allow substitution:

• For EN 10025-2 S235JR: Use ASTM A283 Gr C in US projects.
• For EN 10025-2 S355JR: ASTM A572 Gr 50 for high-strength needs.

Substitution considerations:

• Standards Compliance: EN for Europe (CE marking), ASTM for US (AWS codes).
• Toughness: EN grades have impact testing; ASTM may not, requiring supplements for cold use.
• Cost/Availability: EN in Europe, ASTM in US; Gangsteel bridges this with dual-certified plates.

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