CR20NI80 High-Purity NiCr, NiCrFe Alloys

Ang pangunahing sikreto sa likod ng kakayahan ng CR20NI80 high-purity na NiCr at NiCrFe alloys na gumana nang mapagkakatiwalaan sa mataas na temperatura para sa pinalawig na mga panahon ay nakasalalay sa siksik na chromium oxide na protective layer na nabuo sa ibabaw ng mga ito. Ang pagkakaroon ng nickel ay nagpapahusay sa pagdirikit ng oxide film sa substrate, na pumipigil sa oxide film mula sa pagbabalat sa panahon ng matinding pagbabagu-bago ng temperatura. Ang oxide film na ito ay lubhang manipis ngunit hindi kapani-paniwalang siksik, na epektibong pumipigil sa mga panlabas na atomo ng oxygen mula sa diffusing sa mas malalim na mga layer ng substrate. Kapag nasira ang ibabaw, ang chromium sa substrate ay mabilis na lumilipat sa ibabaw at binabago ang proteksiyon na layer. Kahit na ang linear expansion coefficient nito na 18 × 10⁻⁶/℃ ay bahagyang mas mataas kaysa sa bakal, ang thermal expansion na proseso nito ay nagpapakita ng mataas na linear na katangian. Nangangahulugan ito na maaaring maisagawa ang tumpak na pisikal na pagmomodelo kapag nagdidisenyo ng mga istrukturang sumusuporta sa elemento ng pag-init ng malalaking pang-industriya na electric furnace, pag-iwas sa pagbaluktot ng elemento o mga short circuit na dulot ng thermal stress.
