The notched tensile properties of AC4CH alloy, which was often used for structual parts were investigated. The following results were obtained. The notch coefficient was less than 1 and notch-sensitivity was negative. The notch coefficient increased slightly as defects increased. The notched yield ratio, which corresponded to fracture toughness, decreased with increasing 0.2% proof stress, while the notched yield ratio increased with decreasing Fe content.
