Okuqukethwe kwe-nickel ephezulu kunikeza i-alloy esebenzayo ukumelana nokugqwala kwengcindezi.
Ukumelana nokugqwala kuhle emithonjeni ehlukahlukene, njenge-sulfuric, phosphoric, nitric kanye ne-organic acid, izinsimbi ze-alkali ezifana ne-sodium hydroxide, i-potassium hydroxide ne-hydrochloric acid.
Ukusebenza okuphezulu okuphezulu kukonke kwe-Incoloy 825 kuboniswa kusincibilikisi senuzi esinemithombo yezindaba ebolayo ehlukahlukene, njenge-sulfuric acid, i-nitric acid ne-sodium hydroxide, konke kucutshungulwe endaweni efanayo.

I-825 alloy iwuhlobo lwe-alloy yobunjiniyela obujwayelekile, enokumelana nokugqwala kwe-asidi ne-alkali endaweni ye-oxidation kanye nokunciphisa kanye nokumelana ngokuphumelelayo nokuqhekeka kwe-corrosion ngenxa yokwakheka kwayo okuphezulu kwe-nickel.Kuzo zonke izinhlobo zemidiya, ukumelana nokugqwala kuhle kakhulu njengesibabule. i-asidi, i-phosphoric acid, i-nitric acid ne-organic acid, kuya ku-alkali, njenge-sodium hvdroxide, i-potassium hvdroxide nesisombululo se-hvdrochloric acid.Ukusebenza okuphelele okuphezulu kwe-825 alloy kubonisa kusincibilikisi esivuthayo se-nuclear se-corrosion medium ehlukahlukene, njenge-sulfuric acid, i-nitric acid ne-sodium hvdroxide konke kuphathwa ngendlela efanayo.
