kan-thal D fecral hlau alloy

Kanthal hlau yog ib qho ferritic hlau-chromium-aluminium (FeCrAl) alloy. Nws tsis yooj yim xeb lossis oxidize hauv kev siv hauv kev lag luam thiab muaj kev tiv thaiv zoo heev rau cov ntsiab lus corrosive.

Cov hlau Kanthal muaj qhov kub siab tshaj plaws ua haujlwm dua li cov hlau Nichrome. Piv rau Nichrome, nws muaj qhov hnyav dua ntawm qhov chaw, tiv taus siab dua, muaj zog dua, thiab qhov ceev qis dua. Cov hlau Kanthal kuj kav ntev dua 2 txog 4 npaug dua li cov hlau Nichrome vim nws cov khoom oxidation zoo dua thiab tiv taus cov chaw sulfuric.

Kanthal Dsiv rau qhov kub txog li 1300 ° C (2370 ° F).

Hom hlau Kanthal no tsis tiv taus sulfuric corrosion thiabKanthal A1. Kanthal DCov hlau feem ntau pom muaj nyob rau hauv cov khoom siv hauv tsev xws li cov tshuab ntxuav tais diav, cov khoom siv ceramic rau cov cua sov vaj huam sib luag, thiab cov tshuab ntxhua khaub ncaws ziab khaub ncaws. Nws kuj tseem tuaj yeem pom muaj nyob rau hauv kev siv hauv kev lag luam, feem ntau yog nyob rau hauv cov khoom siv cua sov rau lub cub tawg. Kanthal A1 feem ntau raug xaiv rau cov ntawv thov rau lub cub tawg loj dua vim nws qhov kev tiv taus siab, kev tiv taus corrosion zoo dua, thiab kub thiab nkag siab dua. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm Kanthal A1 dhau Kanthal D yog qhov tseeb tias nws tsis yooj yim oxidized.

Nyob ntawm seb qhov resistivity xav tau, qhov kub siab tshaj plaws ua haujlwm, thiab qhov xwm txheej corrosive ntawm cov khoom, koj yuav xav xaiv Kanthal A-1 lossis Kanthal D hlau.
