EN10155 S355J0W weathering steel plate generally adopts the process route of fine material feeding into the furnace - smelting (converter, electric furnace - microalloying treatment - argon blowing - LF refining - low superheat continuous casting (feeding rare earth wire) - controlled rolling and controlled cooling. When the steel scrap is added to the furnace together with the charge, it is smelted according to the conventional process.
Deoxidizers and alloys are added after tapping, and the molten steel is cast after argon blowing treatment. Due to the addition of rare earth elements to the steel, the EN10155 S355J0W weathering steel plate is purified and the inclusion content is greatly reduced.
Due to the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from infiltrating into the steel matrix, slowing down the deep development of corrosion into the steel material, and greatly improving the atmospheric corrosion resistance of EN10155 S355J0W weathering steel plate.
EN10155 S355J0W weathering steel plate is a steel series that can be used in thinning, exposed use or simplified coating, so as to prolong the corrosion resistance of products, save labor and reduce consumption, and upgrade. The steel system that makes it sustainable and innovative.
