Ruvara rweOxidation Chromel Mutsetse weChromium weNickel weSimbi dzeKusonesa

Tsananguro pfupi:

Chromel A imhando yenickel-chromium alloy inoshandiswa pakupisa kunosvika 1200°C. Inoshandiswa mumhepo inoodza muviri yakaita senitrogen, ammonia, mhepo isina kugadzikana ine sarufa nesarufa. Chromel A ine hunhu hwakanyanya hunodzivirira kupisa kupfuura Iron-aluminium alloys.
