Research on Post-weld Heat treatment and Property of Welded Joint of 15NiCuMoNb5-6-4 Steel

ZHENG Zhunbei1,WANG Bo1,ZHANG Bing1,WANG Rui2(1.Research Station of Material Technology,Shaanxi Electric Power Research Institute,Xi'an 710054,China;2.Xi'an North Huashan Mec.& Elec.Co.,Testing Center,Xi'an 710043,China)  
The mechanical properties of welded joint of 15NiCuMoNb5-6-4 steel were studied.The results show that the microhardness of welding seam of 15NiCuMoNb5-6-4 steel can't be improved by raising tempering temperature and prolonging holding time.The tensile strength and impact property of the welded joint still meet the standard of design,although the microhardness of welding seam is less than that of the base metal.
