S355J0
1.0553Non-alloy structural steel with 355 MPa min yield and 27J impact at 0°C. The "J0" variant between JR (+20°C) and J2 (-20°C). Former designation St52-3U (DIN 17100). Good weldability (CEV ≤0.47). Used for bridges, cranes, buildings, wind turbines, heavy machinery frames, and general structural applications requiring moderate low-temperature toughness.
