The influence of dual‐phase structure (ferrite + martensite) on the impact toughness and rate of abrasive wear for as‐cast and normalized steel (0.29 C, 1.15 Mn, 0.9 Si and 0.95% Cr) is investigated. The increased grain refinement and the well arranged lamellar packets of martensite and ferrite obtained during intercritical quenching (from 810°C) of normalized and prequenched (from 880°C) steel created a satisfactory combination between toughness and abrasive wear resistance over those measured for intercritically quenched as‐cast steel with or without prequenching.
