A steady torque density increase in the wind industry requires continuous advancement in design and materials. High torque density ratios lead to the use of high-strength nodular cast iron in gearbox parts where until now it has not been necessary to use them. To facilitate the characterization of those materials, taking into account the difficulty of extracting material samples directly from heavy section castings, a dedicated geometry and its manufacturing process are proposed. On the basis of a casting trial, the mechanical property predictions of an EN-GJS-500-14 grade are adjusted following a working methodology that could help to optimise the performance of the different nodular cast iron grades in a high torque density scenario.
