|A Test Comparision for Vessel Studs Forging Tempering followed by between still Air Cooling and Oil Cooling
China Nuclear Power engineering Co. Ltd.
|A test comparision for vessel studs forging tempering followed by between still air cooling and oil cooling is introduced in the paper, which includes chemical analysis, metallographic examinations and mechanical tests at two cooling. It is proved that in heat process shop, vessel studs forging by tempering followed by oil cooling is with better mechanical and integrated properties than by tempering followed by still air cooling and vessel studs forging by tempering followed by oil cooling is feasible.
