Ua tofia e avea ma UNS N08825 poʻo DIN W.Nr. 2.4858, Incoloy 825 (lea e taʻua o le "Alloy 825") o se uʻamea-nickel-chromium faʻatasi ma faʻaopoopoga o le molybdenum, cooper ma le titanium. O le fa'aopoopoina o le molybdenum e fa'aleleia atili ai lona tete'e atu i le fa'a'a'a'a'i i totonu o le fa'a'ele'ele o le vai a'o mea e maua ai le 'apamemea e tu'uina atu ai le tete'e atu i le sulfuric acid. Fa'aopoopo le Titanium mo le fa'amautuina. O le Alloy 825 e sili ona tete'e i le fa'aitiitia ma le fa'ama'iina o vaila'au, i le fa'amamafaina o le fa'amamafa, ma le osofa'iga fa'apitonu'u e pei o le pitting ma le ga'o. E sili ona tetee i sulfuric ma phosphoric acids. Incoloy 825 alloy e masani ona faʻaaogaina mo le gaosiga o vailaʻau, paipa petrochemical, masini faʻaleagaina, paipa suauʻu ma kesi, toe faʻaleleia o suauʻu faaniukilia, gaosiga o vailaʻau, ma meafaigaluega piki.
