What Material is EN 10025 S275 Equivalent To?

As a leading exporter and manufacturer of high-quality structural steel plates, Gangsteel specializes in producing EN 10025-compliant materials, including the S275 steel grade.

S275 is a non-alloy structural steel under EN 10025-2, widely used for general construction and welded applications due to its balanced strength and ductility.

Understanding its equivalent grades in other international standards is crucial for global project compatibility.

Our S275 plates are supplied in as-rolled, normalized, or thermomechanically rolled conditions, depending on the variant.

Overview of S275 Steel

S275 (EN 10025-2, designation 1.0044 for S275JR) is a low-carbon structural steel with a minimum yield strength of 275 MPa (for ≤16 mm thickness). It is available in variants like S275JR (+20°C impact), S275J0 (0°C), and S275J2 (-20°C), offering good weldability and moderate toughness for construction, bridges, and machinery. Unlike fine-grain normalized grades like en 10025 3 s275n normalized structural steel plate, S275 is not specifically designed for extreme low-temperature toughness but suits general-purpose structural needs.

Equivalent grades in other standards are selected based on similar yield strength, tensile properties, and weldability, though impact testing and delivery conditions may vary slightly.

Equivalent Grades to S275

The table below lists the primary equivalent grades for S275 (focusing on S275JR unless noted) in major international standards.

*Note: For low-temperature applications (-50°C), use en 10025 3 s275nl normalized structural steel plate or equivalents like ASTM A633 Gr. A.

Chemical Composition Comparison

S275 and its equivalents share low-carbon profiles for weldability (max % unless noted, ≤100 mm thickness).

*Note: CEV ensures weldability; S275’s low P/S enhance ductility.

Mechanical Properties Comparison

Properties for ≤16 mm thickness, as-rolled or normalized (S275J2/A572 Gr. 42 may be normalized).

*Note: S275 variants (J0: 0°C, J2: -20°C) offer defined impact values; equivalents may need testing for cold applications.

Applications and Substitution Notes

S275 is used in buildings, bridges, and machinery. Equivalents like A36, SS400, and Q235B suit similar general-purpose roles but may lack impact testing unless specified (e.g., A572 Gr. 42 for J2 equivalence). Verify delivery condition and toughness for critical projects. For higher strength, see en 10025 3 s355nl normalized structural steel plate or en 10025 3 s420nl normalized structural steel plate.

Summary

S275 (EN 10025-2) equivalents include ASTM A36, A572 Gr. 42, DIN St 44-2, JIS SS400, and GB Q235B, with yield strengths of 235–290 MPa and tensile strengths of 370–560 MPa. These grades match S275’s general structural use, but S275JR/J0/J2 provide defined impact properties, unlike most equivalents unless specified.

FAQ

What is the closest ASTM equivalent to S275?

ASTM A36 (250 MPa yield) is closest for general use, but A572 Gr. 42 (290 MPa) better matches S275J2 for impact at -20°C.

Is GB Q235B a direct substitute for S275?

Yes, Q235B (235 MPa yield, 370–500 MPa tensile) is a close match for S275JR, but lacks standard impact testing; verify for cold climates.

How does JIS SS400 compare to S275?

SS400 (245 MPa yield, 400–510 MPa tensile) is similar to S275JR but has no mandatory impact test, making it less suitable for low-temperature applications.

Can S275 equivalents be used without additional testing?

For non-critical applications, yes; for low-temperature or high-safety projects, confirm impact properties and delivery condition (e.g., normalized for A572 Gr. 42).

What if I need a low-temperature equivalent to S275?

Use S275NL (EN 10025-3) or ASTM A633 Gr. A for -50°C toughness, as standard S275 equivalents lack guaranteed cold performance.
