yintoni inconel 690#Iconel 690
Izinto ezisetyenziselwa iityhubhu zokudlulisa ubushushu zejenereyitha zomphunga kwizityalo zamandla enyukliya ze-PWR ziye zadlula kwinkqubo yophuhliso, kuquka i-304 austenitic stainless steel, 600 alloy, 800 alloy kunye ne-690 alloy. Uphando malunga nokungaphumeleli kwe-corrosion ye-600 alloy kwinkonzo ibonisa ukuba i-intergranular corrosion kunye ne-intergranular stress corrosion cracking zezona ngxaki ziphambili. I-alloy 690 isetyenziswa njengesixhobo sokuhambisa ubushushu kwiijenereyitha zomphunga kwizityalo zamandla enyukliya ze-PWR. Ukusukela oko yasetyenziswa ngeminyaka yoo-1990, akukho monakalo uchaziweyo, kwaye umphumo mhle kakhulu.
