Alloy 825Waxyaabaha ku jira nikkel-ka sare ayaa siinaya alloy-ga wax ku ool ah ee cadaadiska daxalka iska caabbinta.Iska caabinta daxalka waxay ku fiican tahay warbaahinta kala duwan, sida sulfuric, fosfooraska, nitric iyo acids organic, biraha alkali sida sodium hydroxide, potassium hydroxide iyo xalal acid hydrochloric.
Waxqabadka guud ee sare ee Incoloy 825 waxaa lagu muujiyey milmaha gubashada nukliyeerka oo leh noocyo kala duwan oo warbaahin ah, sida sulfuric acid, nitric acid iyo sodium hydroxide, oo dhamaantood lagu farsameeyay isla qalab.
