Incoloy 825 (Nikeli Alloy 825 / UNS N08825) A'a

Folasaga: Alloy Alloy mo Siosiomaga Vailaau Matautia

Incoloy 825, ua lauiloa foi oNikeli Alloy 825peUNS N08825, ose maualuga-fa'atinoganikeli-u'amea-chromium alloyfaaleleia mamolybdenum, kopa, ma le titanium.
Ua mamanuina faapitoa e faatino i laloacidic, chloride, ma tulaga maualuga -vevela, ma avea ai ma se tasi o mea e sili ona fa'aogaina i vaila'au, petrochemical, ma faiga o le gataifale.

O lo'o fa'aalia e le u'amea se tu'ufa'atasiga seāseā o meatotino:

Lelei le tetee ifa'aitiitiga ma fa'ama'i fa'ama'i(e aofia ai le sulfuric ma le phosphoric acid).
Maumau maualuga faasagapitting, a'a ma'a, ma fa'amamafa -ta'e.
Matagofie faatinoga ina ua mavaeu'amea po'o le fa'a'umi'umii le maualuga o le vevela.

O lona fa'atuatuaina ua avea ai le Alloy 825 ma mea e sili ona fiafia i aifa'afesuia'i vevela, condenser, evaporators, ma paipa i fafo, lea e ola faatasi ai le pala ma le vaivai o masini.

Fua'iga vaila'au ma le mautu

O le faʻatinoga o le Alloy 825 e afua mai i lona paleni faʻaeteete faʻatulagaina:

Elemene	Anotusi (%)	Matafaioi Metallurgical
Nikeli (Ni)	38.0 – 46.0	Tete'e a'a, mautu fausaga
Chromium (Cr)	19.5 – 23.5	Oxidation tete'e, fa'avae ata tifaga pasi
Uamea (Fe)	Paleni	Matrix faufale mo le malosi
Molybdenum (Mo)	2.5 – 3.5	Tete'e i le fa'aitiitia o fa'asalalauga ma le pitting
Kopa (Cu)	1.5 – 3.0	Faʻaleleia le teteʻe i sulfuric ma phosphoric acids
Titanium (Ti)	0.6 – 1.2	Fa'amautu e tetee atu i le pala intergranular
Mn, Si, C, S	E itiiti ifo pe tutusa ile 1.0 / 0.5 / 0.05 / 0.03	Tausia le mama ma le mafai ona galue

O lefa'amautu titaniumfaʻamautinoa le teteʻe atu i le faʻalogoina ma le osofaʻiga faʻatasi pe a uma le faʻapipiʻiina poʻo le faʻaalia i le 540-870 tikeri auaunaga siosiomaga.

Fa'agasologa Gaosi ma Togafitiga vevela

Incoloy 825 paipa ma paipa ua gaosia e ala isa'o-pulea liusuavai, fai, ma vaifofo vaie fa'amautinoa ai le fa'aogaina o le microstructure ma le amio sili atu le pala.

Oloa Fa'agasologa Va'aiga

Vacuum po'o Argon Melting– Aveese mea le mama ma taofia le tu'ueseeseina a'o fa'afefiloi.
Aveesega vevela / Tusia malulu- Faʻamautinoa le faʻatonutonuina o fua ma le faʻaogaina.
Uilaina Orbital Otometi(mo ituaiga uelo) – Fausia su'iga lelei, fa'ato'a ulu.
Fofo Fa'asusu (940–980 tikeri)- Faʻamavaeina carbide ma toe faʻafoʻisia le ductility.
