Nickel-chrome hlau rau hluav taws xob phuam khib (Cr20Ni80)

Me me resistivity, siab kub lub zog; zoo welding thiab kev ua tau zoo; tsis muaj kev hloov pauv loj hauv cov cuab yeej cuab tam ntawm qhov kub thiab txias 2. Kev ua haujlwm siab tshaj plaws: 1000-1050 degrees Celsius 3. Tom qab qhov kub ntawm 1050 degrees, lub toughness yog zoo, thiab nws tsis yooj yim rau tawg. 4. Qhov kev hloov pauv hloov tom qab kub siab feem ntau yog 6-8 feem pua ​​. Lub zog kuj ruaj khov thaum siv. 5. Feem ntau, cov kav dej kub kub yog tsim los ntawm nickel-chromium hlau. Nws tsuas yog muaj cov nickel thiab chromium Cheebtsam, uas tsis yooj yim rau oxidized ntawm qhov kub thiab txias thiab muaj lub neej ua haujlwm ntev.
