【Abstract】 The investigation on A508-3 steel and its welding materials and processes was conducted. The contents includ 6 items of physical parameter measurement of base metal, 10 items of acceptable property requirement, 21 tests and 11 studies. The manufacture for the simulated products of reactor pressure vessel core sheel and steam generator tube plate for NPP of 600 MWe-PWR is described. The acceptance requirements and actual mechanical properties are given, which obtained from the base metal forgings, weld metal, heat affected zone, and overlaid weld metal of the two simulated products; the results of fast neutron irradiation test are given as well. It is commented that China has grasped the essential technology of producing the base metal and welding materials , welding and clading technology and non-destructive test, based on the productions of A508-3 steel forgings, welding materials, two simulated products, and the actual mechanical properties; the main equipments on nuclear island are able to be manufactured in China.更多还原
