Cov kev qhia dav rau Nickel-based superalloys: Incoloy 825 (tsis yog n08825 / w {}. 2.4858)
Dab tsi yog Incoloy 825?
Tsim raws li tsis ua N08825 lossis dm w {1} {{{{{{{2} {{{{{{{ Cov ntawv thov, thaum lub ntsiab lus tooj liab cuam tshuam rau cov sulfuric kev tawg, thiab oxidizing corrosion {} Nws tshwj xeeb yog tiv thaiv sulfuric thiab phosphoric acids {{{}}} ecloy yog feem ntau siv hauv cov khoom siv tshuaj lom, thiab roj peting ua thiab pickling khoom .
Cov yam ntxwv ntawm Incoloy 825 (tsis yog n08825 / w. . 2.4858):
(1) Zoo tsis kam rau kev ntxhov siab corrosion backing .
(2) Zoo tsis kam rau pitting thiab crevice corrosion .
(3) zoo tsis kam mus rau oxidation thiab tsis-oxidizing kub kua qaub .
(4) Cov khoom siv zoo rau ntawm chav tsev kub thiab kub hauv qab 550℃.
(5) Muaj pov thawj rau cov nkoj siab nrog kev tsim cov kub txog li 450 degree.
Lub luag haujlwm ntawm txhua lub ntsiab hauv 825 alloy
Ni: Lub luag haujlwm ntawm NI yog txhawm rau txhim kho cov alloy qhov tsis kam mus rau chloride kev ntxhov siab corrosion {}}
Lub luag haujlwm ntawm chromium: cr muab cov tsis kam mus rau oxidizing ib puag ncig .
Titanium: ntxiv 0 {{. 6% -1.2}}}}}}}}}.
Molybdenum: Ntxiv 3% MO tuaj yeem txhim kho lub peev xwm los tiv thaiv pitting hauv dej corrosion.
Copper: Adding 1.5%-3.0% Cu makes the alloy resistant to sulfuric acid corrosion.
Daim ntawv thov teb Nickel-based alloy incoloy 825 (tsis yog n08825 / w {{} {4 4}})
Incoloy 825 alloy tuaj yeem siv rau hauv cov kev daws teeb meem corrosive, suav nrog cov kua roj oxiduric, suav nrog cov ntsev roj qaub rau cov suldoling {}} ecolized seaterater corrosion Kuj .
(1) Kev kho tshuaj:
Kev Txauv Tshav Kub Kub, cov yeeb nkab fittings, evapators, cov kav dej, cov roj av, cov hnab ris, ntim khoom tso tsheb tso cia thiab thawv tso tsheb hlau luam; Ua thiab kev thauj mus los ntawm sulfuric acid, phosphoric acid, hydrochloric acid, nitrites acid, nitrites thiab oxidized salts .
(2) Pulp thiab papermaking:
Ntub dej txuas nrog hauv sodium sulfate thiab sodium bisulfite kua tshuab.
(3) Kev Kho Mob Picking:
Acid tank cua sov thiab nuv clamps .
(4) ore Hnav ris tsho: Phaj Cov Hluav Taws Xob Tshav Kub hauv Hydrometallurgy thiab tooj liab ua kom zoo.
(5) Kev tswj qias neeg: pub hauv qab thiab discs ntawm electrostatic precipitators; Kav dej thiab baffles, flue roj raceaters, khib nyiab kub kev sib pauv hloov pauv, chimney hnab twb qhib thiab lwm yam ntub dej sab nraud; Cov khoom seem ntawm cov tshuab hluav taws xob, ntub dej. Tubrog marine iner roj tshuab; Tshuab ntxhua khaub ncaws khov kho tshuab ntxhua khaub ncaws .
