EN 10025-3 S275N Steel Plate for sales

What is EN 10025-3 S275N Steel?

EN 10025-3 S275N steel plate is a low-alloy, fine-grained structural steel designed for weldable applications in moderate-temperature environments. It conforms to the European standard EN 10025-3, specifying technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels. The typical delivery condition is normalized or normalized rolled, which refines the microstructure for improved toughness and uniformity.

The designation "EN 10025-3 S275N" means:

• S: Stands for "structural steel."
• 275: Indicates the minimum yield strength of 275 MPa for thicknesses up to 16 mm.
• N: Refers to the normalized or normalized rolled heat treatment.

As a fine grain structural steel, EN 10025-3 S275N achieves controlled grain size for better impact resistance, weldability, and formability, making it a versatile choice for general construction projects.

What is the Difference Between EN 10025-3 S275N and S275NL / S275M / S355?

These distinctions help tailor material choices:

• EN 10025-3 S275N vs S275NL: Equivalent strength levels, but S275NL ensures impact toughness at -50°C (vs -20°C for EN 10025-3 S275N), better for extreme cold like northern pipelines. Learn more about EN 10025-3 S275NL normalized structural steel plate.
• EN 10025-3 S275N vs S275M: S275M utilizes thermomechanical controlled processing (TMCP) for enhanced grain refinement and economy in welding, contrasting EN 10025-3 S275N's normalization for versatile processing.
• EN 10025-3 S275N vs S355: S355 achieves higher yield (355 MPa vs 275 MPa) for optimized weight and strength, at higher cost; EN 10025-3 S275N is budget-friendly for standard builds. Visit EN 10025-3 S355N normalized structural steel plate.

Considerations include temperature exposure, cost, and fabrication ease.

Welding and Heat Treatment of EN 10025-3 S275N

With its low CEV, EN 10025-3 S275N welds effortlessly using GMAW or SAW, adhering to EN 1011-2 standards.

• Preheating: Generally not needed for ≤20 mm; 50-100°C suggested for thicker plates to minimize hydrogen risks.
• Post-Weld Heat Treatment (PWHT): Rarely required; stress relief at 520-580°C optional for high-stress areas.

Preferred fillers:

• GMAW: ER70S-6 (AWS A5.18).
• SAW: EM12K flux paired with EH14 wire.

This promotes durable, defect-free welds.

FAQ

Is EN 10025-3 S275N steel good for welding?Yes; CEV ≤0.40% allows simple arc welding with no special requirements.

What temperature can EN 10025-3 S275N be used in?Suitable from -20°C to +400°C, with verified toughness at -20°C; opt for S275NL below that.

Does EN 10025-3 S275N require preheating when welding?No for thin sections (≤20 mm); light preheat (50-100°C) for thicker to ensure quality.

Is EN 10025-3 S275N equivalent to ASTM A572?Approximate to A572 Grade 50 (yield ~345 MPa equivalent), but EN 10025-3 S275N's normalization adds superior toughness; not a perfect match.

What is the maximum thickness available for EN 10025-3 S275N?Reaches 250 mm, with properties tapered for thicker plates to uphold standards.

Can EN 10025-3 S275N be used in construction in temperate climates?Ideal; its balanced properties suit bridges, buildings, and machinery in regions above -20°C.

What is the difference between EN 10025-3 S275N and EN 10025-2 S275JR?EN 10025-3 S275N is normalized fine-grain for -20°C impact, while S275JR (EN 10025-2) is basic hot-rolled without low-temp guarantees.

How does EN 10025-3 S275N compare to Chinese Q275N?Q275N is a near-equivalent with matching strength and -20°C performance, but EN 10025-3 S275N ensures stricter EU controls on composition and testing.
