Nickel Alloy GH4738 nigikorwa kinini, nikel-ishingiye kuri superalloy yagenewe kuba indashyikirwa mubidukikije bisabwa cyane. Nimbaraga zayo zisumba izindi, kurwanya bidasanzwe okiside no kwangirika, hamwe n’umutekano udasanzwe ku bushyuhe bwo hejuru, GH4738 ni byiza gukoreshwa mu kirere, mu mashanyarazi, no mu zindi nganda zisaba imikorere yizewe mu bihe bikabije. Iyi mavuta itanga imbaraga zidasanzwe zo guhangana nimbaraga zumunaniro, zitanga igihe kirekire kandi neza. Hitamo Nickel Alloy GH4738 kubikorwa byawe bikomeye byo hejuru yubushyuhe kandi ubone uburambe butagereranywa bwo kwizerwa no gukora.

Ibiranga ibicuruzwa

GH738 ni nikel ishingiye ku bushyuhe bwo hejuru cyane ikomantazwa n’imvura igwa, hamwe n’imvura nziza yo kurwanya ruswa, imbaraga nyinshi n’umutungo w’umunaniro, uburyo bwiza bwa plastike kandi butunganijwe neza. Ikoreshwa cyane muri moteri yindege izunguruka ibice, gukoresha ubushyuhe ntiburenze 815 ℃. Irashobora kubyara amasahani akonje kandi ashyushye, imiyoboro, imirongo, insinga, kwibagirwa, guta no gufunga.
