S275JR is a European hot-rolled structural steel specified under EN 10025-2:2019. With 275 MPa minimum yield strength—approximately 10% higher than S235 and ASTM A36—it enables lighter structural designs while maintaining excellent weldability....
S275JR ist ein European heiß-rolled structural steel specified unter EN 10025-2:2019. Mit 275 MPa minimum yield strength—approximately 10% higher als S235 und ASTM A36—es enables lighter structural designs while maintaining excellent weldability. Der 'JR' designation guarantees 27 Joules impact energy bei +20°C, sufficient für indoor und temperate-climate structures. Widely used across EU construction, bridge building, und allgemein engineering wo Eurocode design standards apply.

Frequently Asked Questions
Was ist der difference zwischen S275JR und S355J2?
S355J2 offers significantly higher yield strength (355 MPa vs 275 MPa) und guaranteed impact toughness bei -20°C (27 Joules minimum). S275JR ist suitable für allgemein construction; S355J2 ist preferred für dynamically loaded structures und kalt-climate applications. S355 adds approximately 30% mehr load-bearing capacity für der gleich abschnitt size.
