Inconel 690 ASTM SB167 UNS N06690 Nickel Based Alloy Seamless Pipe W.Nr.2.4642
Inconel 690 UNS N06690 nickel based alloy seamless pipe W.Nr.2.4642
Material designation: Inconel 690 nickel based alloy
German grade: W.Nr.2.4642
US grade: N06690
Inconel 690 (N06690) nickel-based alloys are mainly used:
Inconel 690 (UNS N06690) nickel-based alloy is mainly used for the
material of the heat transfer pipe of the steam generator of the
PWR nuclear power plant. It is the core technology of the steam
generator. At present, among the pressurized water reactor nuclear
power plant units in operation in China, only Qinshan Phase I uses
800 alloy, and Qinshan Phase II, Daya Bay and Ling'ao nuclear power
plants all use 690 alloy as the steam generator heat transfer tube
material. Most of the pressurized water reactor nuclear power
plants under construction and planning also use 690 alloy as the
material of the steam generator heat transfer pipe.
