Understanding S275NL and Its Global Equivalents

S275NL (EN 10025-3, designation 1.0491) is a low-alloy, fine-grain structural steel with a minimum yield strength of 275 MPa and excellent impact resistance down to -50°C. It is widely specified for welded constructions where low-temperature performance is critical.

When sourcing internationally, understanding equivalent grades in other standards like ASTM, DIN, and JIS is crucial for seamless project integration. These equivalents are selected based on similar chemical composition, mechanical properties, and delivery conditions (normalized or as-rolled). However, always verify specific requirements, as minor variations in thickness or testing may apply.

Gangsteel supplies S275NL and its equivalents with full traceability and certifications, supporting cross-standard substitutions.
