| Abstract: | The microstructure and corrosion-resistance of a new double stainless steel for pumps used in seawater were studied. The metallurgical structure of the steel was observed and analyzed by means of metallurgical microscope and X-ray diffraction.The result of manifold corrosion tests shows that the steel possesses good uniform corrosion resistance in seawater and good intergranular corrosion resistance, and its pitting corrosion resistance is higher than that of C15 steel. |
