The invention discloses a casting high in abrasion resistance and belongs to the field of casting. The casting high in abrasion resistance is formed by pouring liquid metal. The liquid metal comprises 99.3-99.5% of 2Crl3 and 0.5-0.7% of Mo. The casting formed by pouring the liquid metal in the component proportion is good in abrasion resistance, so that the problems that in the prior art, the abrasion resistance of a casting is poor, and therefore the casting quality is affected are solved; the abrasion resistance of the casting is fundamentally improved, the service life of the casting is guaranteed, and therefore the application range of the casting is widened.
