Cov Hlau Uas Muaj Tshuaj Lom Neeg Thiab Cov Hlau Uas Muaj Nqis Heev Uas Siv Tau Rau Kev Siv Tshuaj Lom Neeg Thiab Rau Cov Hlau Uas Siv Tau Rau Kev Ua Kub Duab Tshwj Xeeb
  • Cov Hlau Uas Muaj Tshuaj Lom Neeg Thiab Cov Hlau Uas Muaj Nqis Heev Rau Kev Xeb Ni35Cr20

Cov Hlau Uas Muaj Tshuaj Lom Neeg Thiab Cov Hlau Uas Muaj Nqis Heev Rau Kev Xeb Ni35Cr20

Kev Piav Qhia Luv:

Ni35Cr20 (1.4860) siv tau rau qhov kub thiab txias txog li 1000°C. Ni35Cr20 tshwj xeeb tshaj yog muaj zog tiv taus thiab tus nqi qis dua piv rau lwm cov hlau nickel-chromium. Txawm hais tias nws muaj cov hlau ntau, Ni35Cr20 tiv taus kev oxidation thiab kev xeb tshuaj lom neeg. Ni35Cr20 tsis yog hlau nplaum.

    Cov Lus Nug Feem Ntau

    Cov Cim Npe Khoom

         NiCr35 20 (1.4860) yog siv ua cov khoom siv hluav taws xob hauv cov khoom siv hauv tsev thiab lwm yam khoom siv hluav taws xob cua sov. Nws muaj kev ywj pheej zoo tom qab siv ntev, cov khoom siv kho tshuab zoo ntawm qhov kub siab thiab weldability zoo. Qhov kub ua haujlwm siab tshaj plaws hauv huab cua yog + 600 ° C thaum siv rau cov xov hlau tiv thaiv thiab + 1050 ° C thaum siv rau cov xov hlau cua sov.

    • cov resistors hluav taws xob muaj nqis siab thiab rau cov xov hlau cua sov.
