After actual promotion and inspection, they can be widely accepted and recognized by the market .

Description

technical field [0001] The invention relates to a high-toughness wear-resistant material applied to an impeller, which belongs to the field of chemical industry. Background technique [0002] The main flow components in the mud pump not only have to withstand the corrosion of sea (river) water and sand wear, but also sometimes encounter severe working conditions of severe impacts from pebbles and broken rocks. Therefore, it is required that the material of the flow-passing parts (especially the impeller) should not only have certain corrosion resistance and wear resistance, but also have high toughness. In the past, high-chromium cast iron was mostly used for mud pump flow parts, and its Rockwell hardness was controlled above 58HRC, and its impact toughness was above 58HRC. Its wear resistance is excellent, but its toughness is insufficient. Especially when the large-scale mud pump is in the working condition of twisting cobblestones and crushing rocks, the impeller is ex...
