摘要：

In order to evaluate the performance of high-Cr cast-steel (15.4% Cr), as a pump casing material, abrasive wear, hardness, corrosion, erosion-corrosion resistance were examined and compared with grey cast iron eventually used. The results obtained were analyzed on a microstructural basis with respect to Cr content of the matrix, amount and types of carbides and the extent of surface passivation. Martensitic high-Cr steel has shown a better performance than grey cast iron.
