S355J2 ist der higher-strength structural steel in EN 10025-2, providing 29% higher yield strength als S275JR. Der J2 designation guarantees 27J minimum Charpy impact energy bei -20°C — wesentlich für dynamically loaded structures und kalt-climate construction across Northern Europe. Dies ist der standard grade für bridge construction, offshore platforms, und wind turbine towers in European practice.

Frequently Asked Questions
S355J2 vs S355JR — wenn sollte I upgrade zu J2?
Specify J2 wenn der structure werden sein exposed zu temperatures unter 0°C während sein service life. JR (20°C impact) ist acceptable für indoor oder temperate-climate structures. J2 (-20°C) ist erforderlich für outdoor structures in Northern/Central Europe, bridges, und any structure subject zu dynamic loading wo brittle fracture bei niedrig temperature ist ein design concern.
