The effects of RE (La and Ce) on toughness of 30CrMnSi wear‐resistance cast steel have been investigated by means of analysing microstructures and mearsering the properties of the steel with and without RE. The results show that RE can refine the as‐cast microstructures, hinder or eliminate needle and network ferrite, increase the dislocation density and the quantity of dislocated martensite, and improve the shape and distribution of inclusions. Therefore the mechanical properties of the steel can be greatly enhanced, especially the toughness of the steel.
