Muxuu yahay Inconel 690

Sababtoo ah iska caabbinta daxalka sare ee warbaahinta acidic, waxaa sidoo kale loo isticmaali karaa in lagu farsameeyo nitric acid, nitric acid + hydrofluoric acid iyo qalabka kale ee kiimikada iyo qaybaha.

Qalabka loogu talagalay tuubooyinka wareejinta kulaylka ee matoorayaasha uumiga ee PWR tamarta nukliyeerka ayaa soo maray geeddi-socod horumarineed, oo ay ku jiraan 304 austenitic birta, 600 alloy, 800 alloy iyo 690 alloy. Cilmi-baaris ku saabsan fashilka daxalka ee 600 aluminium ee adeegga ayaa muujinaya in daxalka intergranular iyo dildilaaca cadaadiska intergranular ay yihiin dhibaatooyinka ugu waaweyn. Alloy 690 waxa loo isticmaalaa sidii tubbada wareejinta kulaylka loogu talagalay dhaliyaasha uumiga ee dhirta tamarta nukliyeerka ee PWR. Tan iyo markii la isticmaalay 1990-meeyadii, wax khasaare ah lama soo sheegin, saameyntuna waa mid aad u wanaagsan.
