NiCr 8020, Alloy 8020 Nickel Chromium UNS N06003 Cr20Ni80 /W.Nr. 2.4869
Kakaretso
Cr20Ni80 ke alloy ea nickel-chromium, e tsejoang hape e le NiChrome alloy. Alloy ena haholo-holo e entsoe ka 20% chromium le 80% nickel, e nang le botsitso bo phahameng ba mocheso, ho hanyetsa kutu le ho hanyetsa mocheso, ke mofuta oa ho hanyetsa motlakase o futhumatsang motsoako. Sebopeho sa eona se tsitsitse, thepa ea motlakase le ea 'mele e tsitsitse, thepa ea mochine oa mocheso o phahameng, polasetiki e batang ea deformation, weldability e ntle, tšebeliso ea nako e telele e ke ke ea hlahisa fracture ea brittle.
Alloy ea Cr20Ni80 e sebelisoa haholo ha ho etsoa lisebelisoa tsa ntlo le lisebelisoa tsa ho futhumatsa tse nang le mocheso o sebetsang ka tlase ho 1000 ° C, joalo ka li-exchangers tsa mocheso, litofo tse chesang, lionto, licheso tsa motlakase, joalo-joalo, 'me li na le bophelo bo bolelele ba tšebeletso.

Khanyetso ea Corrosion
Corrosion resistance ea Cr20Ni80 ke e 'ngoe ea litšobotsi tsa eona tsa bohlokoa. Sesebelisoa sena sa nickel-chromium alloy se entsoe ka 20% chromium le 80% nickel, 'me boteng ba chromium bo matlafatsa ho hanyetsa ha eona ho bola. Mecha ea litaba e fapaneng ea lik'hemik'hale, Cr20Ni80 e ka sebetsa ka mokhoa o tsitsitseng nako e telele, e bonts'a khanyetso e ntle ea kutu. Ebang e maemong a asiti, alkaline kapa tse ling tse senyang, e ka boloka botsitso bo phahameng.
Cr20Ni80 e na le botsitso bo botle ba mocheso o phahameng, ho bolelang hore khanyetso ea eona ea kutu e bolokiloe le tlas'a maemo a phahameng a mocheso. Ka hona, thepa ena e atisa ho sebelisoa ha ho etsoa likarolo tse sebetsang tsa mocheso o phahameng, tse kang mocheso o phahameng oa mocheso, litofo le li-heaters tsa motlakase.
