The effects of silicon content and austempering conditions on impact strength in austempered spheroidal graphite cast steel (AGS) which had nearly the same Young's modulus as conventioral carbon steels were examined. Impact strength increases with silicon content, attains a peak value at 3. 0%, and then begins to decrease regardless of austempering conditions. Also, there are the optimum austempering conditions against impact strength, those are austempering time of about 1800 seconds and austempering temperature between 620 K and 650 K. Impact strength in AGS is closely related to the amount of retained austenite, all the optimum conditions that yeild maximum impact strength, converge to the direction where the amount of retained austenite increases.
