Alloy 825 (UNS N08825) ni austenitis nikel-fer-chromium ivanze hiyongereyeho molybdenum, umuringa na titanium. Yakozwe kugirango itange ruswa idasanzwe muri okiside no kugabanya ibidukikije. Amavuta arwanya chloride guhangayika-kwangirika no gutobora. Kwiyongera kwa titanium ituma Alloy 825 irwanya ubukangurambaga mu gihe cyo gusudira bigatuma umusemburo urwanya igitero cy’imibumbe nyuma yo guhura n’ubushyuhe mu ntera yakangurira ibyuma bidafite ingese. Ihimbwa rya Alloy 825 risanzwe rya nikel-shingiro, hamwe nibikoresho byoroshye kandi bigasudwa nubuhanga butandukanye.

Alloy 825 (UNS N08825) ni austenitis nikel-fer-chromium ivanze hiyongereyeho molybdenum, umuringa na titanium. Yakozwe kugirango itange imbaraga zidasanzwe kubidukikije byinshi byangirika, haba okiside ndetse no kugabanya.
Nikel iri muri Alloy 825 ituma irwanya ihungabana rya chloride-ruswa, kandi igahuzwa na molybdenum n'umuringa, itanga uburyo bwiza bwo kurwanya ruswa mu kugabanya ibidukikije ugereranije n’ibyuma bisanzwe bya austenitis. Chromium na molybdenum biri muri Alloy 825 bitanga imbaraga zo kurwanya imyanda ya chloride, ndetse no kurwanya ikirere gitandukanye cya okiside. Kwiyongera kwa titanium ituma amavuta arwanya ubukangurambaga muburyo bwo gusudira. Uku guhagarara gutuma Alloy 825 idashobora guhangana nigitero cyimibumbe nyuma yo guhura nubushyuhe bwakunze gukangurira ibyuma bidafite ingese.
Alloy 825 irwanya ruswa mu buryo butandukanye bwibikorwa birimo sulfurike, sulfure, fosifori, nitric, hydrofluoric na acide organic na alkalis nka sodium cyangwa potasiyumu hydroxide, hamwe na chloride acide.
Ihimbwa rya Alloy 825 risanzwe rya nikel-shingiro, hamwe nibikoresho byoroshye kandi bigasudwa nubuhanga butandukanye.

Alloy 825 ifite imiterere yubukanishi kuva cryogenic kugeza ubushyuhe buringaniye. Guhura nubushyuhe buri hejuru ya 1000 ° F (540 ° C) bishobora kuvamo impinduka kuri microstructure izagabanya cyane guhindagurika ningufu zingaruka. Kubera iyo mpamvu, Alloy 825 ntigomba gukoreshwa mubushyuhe aho ibintu bigenda byangirika. Umuti urashobora gushimangirwa cyane nakazi gakonje. Alloy 825 ifite imbaraga zingirakamaro mubushyuhe bwicyumba, kandi ikagumana imbaraga kubushyuhe bwa cryogenic.
