inconel 690 #Inconel 690 ndi chiyani
Zida zopangira machubu otengera kutentha kwa ma jenereta opangira mphamvu za nyukiliya za PWR zadutsa njira yotukula, kuphatikiza 304 austenitic stainless steel, 600 alloy, 800 alloy ndi 690 alloy. Kafukufuku wokhudzana ndi kuwonongeka kwa 600 alloy muutumiki amasonyeza kuti intergranular corrosion ndi intergranular stress corrosion cracking ndizovuta zazikulu. Aloyi 690 imagwiritsidwa ntchito ngati chotengera chotengera kutentha kwa ma jenereta a nthunzi m'mafakitale a nyukiliya a PWR. Popeza idagwiritsidwa ntchito m'ma 1990, palibe kuwonongeka komwe kwanenedwa, ndipo zotsatira zake ndi zabwino kwambiri.
