In this paper, NIMONIC 86 material was tried to apply to exhaust valve for small-sized marine diesel engine. The both structural stability and thermal resistance in high temperature were needed to use the NIMONIC 86 material as exhaust valve for small-sized marine diesel eng ine. The purpose of this study is to investig ate the application of NIMONIC 86 material to exhaust valve of small-sized marine diesel engine by comparing, respectively, SUH 3 and STS 316 materials. As the results, NIMONIC 86 material has intermediate characteristics between SUH 3 and STS 316 materials in terms of the strength in condition of room temperature. Further NIMONIC 86 material was evaluated to have better characteristics than SUH 3 and STS 316 materials in terms of the thermal conductivity.
