S235J2 ist der niedrig-temperature variant von der basic S235 structural steel, mit 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. Compared zu S235JR (impact-tested bei +20°C nur), S235J2 ist specified für outdoor structures in regions mit freezing winter temperatures, dynamically loaded structures, und primär structural members in bridges und buildings wo brittle fracture würde sein catastrophic. Der chemistry ist essentially identical zu S235JR; der difference lies in der mandatory niedrig-temperature impact testing und der resulting quality assurance provided zu der designer.

Frequently Asked Questions
Wenn sollte S235J2 sein specified instead von S355J2?
Choose S235J2 wenn niedrig-temperature toughness ist erforderlich but der higher strength von S355 ist nicht needed—für example, sekundär members (purlins, girts), architectural steel exposed zu kalt climates, oder stiffness-governed designs wo 235 MPa ist sufficient. S355J2 provides der gleich -20°C toughness guarantee mit 50% higher yield strength für strength-governed designs.
