Summary

BS EN 10025-2 S275is a versatile, weldable structural steel with 275 MPa yield strength, available in JR, J0, J2 variants for impact resistance from +20°C to -20°C. It is the go-to grade for cost-effective general construction. For extreme cold (-50°C), upgrade to S275NL.

FAQ

What are the main variants of S275 steel?

S275JR (+20°C, 27 J), S275J0 (0°C, 27 J), and S275J2 (-20°C, 27 J) differ in impact testing temperature but share 275 MPa yield and 410–560 MPa tensile strength (≤16 mm).

How does S275NL differ from S275JR/J0/J2?

S275NL (EN 10025-3) is normalized with finer grain and 27 J impact at -50°C, compared to S275’s -20°C to +20°C testing, making it better for extreme cold.

What is the weldability of S275 grades?

All are highly weldable (CEV ≤0.40–0.42); no preheating needed for ≤40 mm. S275NL’s lower P/S enhance cold welding performance.

What applications suit S275 vs. S275NL?

S275 (JR/J0/J2) is for general construction in moderate climates; S275NL is for cold-climate structures like arctic bridges or offshore platforms.

Can S275 grades be used interchangeably with S275NL?

Not for low-temperature applications; S275NL’s -50°C toughness is critical for extreme cold, unlike S275’s -20°C maximum.
