NB/T 20006.10-2021 Pressurized water reactor nuclear power plant alloy steel - Part 10: Magnesium-nickel-molybdenum steel forgings for pressure vessel and steam generator pipes and orifices
Abstract
This document specifies the manufacturing, testing, inspection, and acceptance requirements for forged manganese-nickel-molybdenum alloy steel parts used in the pressure regulators and steam generators of pressurized water reactors. This document applies to forged manganese-nickel-molybdenum alloy steel parts used in the pressure regulators and steam generators of pressurized water reactors, including pressure regulator manhole seats, fluctuation take-offs, valve take-offs, spray take-offs, and steam generator secondary side manhole seats, feedwater take-offs, etc., as well as manhole covers (including pressure regulator manhole covers and steam generator manhole covers, inspection manhole covers, and handhole covers) made from 16MnNiMo, 18MnNiMo, and 20MnNiMo alloy steel.
