NB/T 20006.2-2021 Nuclear alloy steel for pressurized water reactor plants - Part 2: Magnesium-nickel-molybdenum steel forgings for the reactor pressure vessel components not exposed to intense radiation
Abstract
This document specifies the requirements for the manufacture, testing, inspection, and acceptance of manganese-nickel-molybdenum steel forgings used in the reactor pressure vessel cylinders of pressurized water reactor nuclear power plants that are not subject to intense radiation. This document applies to 16MnNiMo alloy steel forgings used in the reactor pressure vessel cylinders of pressurized water reactor nuclear power plants that are not subject to intense radiation, which are manufactured from solid steel ingots. It does not apply to the flange-manhole section of the reactor pressure vessel.
