4. Tlhaloso:
AL6XN ke tšepe e sa hloekang ea super austenitic e hanyetsanang hantle le chloride pitting, crevice corrosion le stress corrosion cracking.
AL6XN ke motsoako oa 6-molybdenum o entsoeng le ho sebelisoa libakeng tse senyang haholo. Nickel ea eona e phahameng (24%), molybdenum (6.3%), nitrogen
'me likahare tsa chromium li e fa khanyetso e ntle ka ho fetesisa ea chloride stress corrosion cracking, chloride pitting le e ntle ka ho fetesisa e thibelang kutu ka kakaretso.
AL6XN e sebelisoa haholo-holo ho ntlafatsa li-pitting le li-crevice corrosion properties tsa chloride. Ke tšepe e sa hloekang e ka chesehang e ka chesehang.
Ka lebaka la litaba tsa eona tsa naetrojene, AL6XN e na le matla a holimo ho feta litšepe tse tloaelehileng tsa austenitic, ha e ntse e boloka ductility le tšusumetso e phahameng.
