A709 grade 50S bridge steel plate, 09CrCuSb steel has the following advantages: 1. The alloy ratio is optimized and rare alloy is added. The finished steel product has excellent sulfuric acid uniform corrosion resistance. 2. The content of As, Sn, Pb and other elements, and the gas content of hydrogen, oxygen and nitrogen are controlled to improve the purity of the billet. According to the analysis of many times, the grain size of the material is not coarser than grade 6. The corrosion resistance of the equipment made of 09CrCuSb steel is improved, and the maintenance cycle is relatively prolonged, which has great economic benefits.
