Material
Steel S355J2 (1.0577)
CNC-machined steel S355J2 is a higher-strength European structural steel, offering roughly 50% greater yield strength than S235JR, with guaranteed toughness down to -20 °C for demanding structural and cold-environment applications.
Manufacturing processes
About
S355J2 (1.0577) is a non-alloy structural steel under EN 10025-2, the European equivalent to ASTM A572 Grade 50.
Compared to S235JR, it offers roughly 51% higher yield strength, allowing smaller cross-sections for the same load, and its "J2" designation guarantees impact toughness of 27J at -20 °C. It retains good weldability, though slightly reduced versus lower-carbon S235JR.
This steel is suitable for bridges, cranes, heavy machinery frames, and structural components exposed to low temperatures or higher loads.
