S355J2 ist der meiste specified hoch-strength carbon structural steel in European construction, mit 355 MPa minimum yield strength und guaranteed Charpy V-notch impact toughness von 27 Joules bei -20°C. Der J2 designation ensures reliable leistung in kalt climates ohne brittle fracture risk. Used extensively in bridges (including der Øresund Bridge), offshore wind turbine foundations, hoch-rise building frames, und heavy machinery. Es welds mit matching-strength electrodes (E7018 oder equivalent) und requires preheat nur über 30 mm thickness.

Frequently Asked Questions
Wie tut S355 compare zu S275 für kosten-effectiveness?
S355 ist approximately 8-12% mehr expensive per ton als S275 but delivers 29% higher yield strength. Für strength-governed designs, S355 typically reduces total structural weight durch 15-25%, resulting in net kosten savings. Für stiffness-governed designs (deflection limits), S275 kann sein mehr economical seit beide grades haben identical elastic modulus (210 GPa).
