In this article, white wear-resistant cast irons of the grades 280H29NL and 300H32N2M2TL are investigated, the chemical compositions and their structures are compared. It has a composition close to eutectic, but is prone to brittle chipping. At high magnifications in the metal base, the places of chipping are found, and where the chipping has not yet passed, gray sulphides are clearly visible. The carbide sizes of the cast irons under investigation vary widely from 8.6 μm to 31 μm.
