S355JR hot rolled carbon steel flat bar adopts innovative asynchronous rolling technology, which forms a gradient performance distribution in the width direction through differentiated roll speed control, increasing the edge strength by 20% while maintaining excellent formability in the central area. Its unique online heat treatment system achieves precise control of grain size to the range of 5-7μm.
S355JR flat bar utilizes an AI surface quality warning system to monitor the morphology of iron oxide scales in real-time through laser 3D scanning, with a defect recognition accuracy of 99.5%. The low yield ratio formula developed through innovation ensures that the yield ratio of the S355JR material is stably controlled below 0.85.
As a new generation structural material, S355JR steel has passed the latest EN 10025 certification and achieved a breakthrough of reducing weight by 30% in the field of photovoltaic brackets, successfully applied to multiple floating photovoltaic power station projects.
