  • Iska caabin Oksaydh oo Wanaagsan NiCr 70/30 oo loogu talagalay fiilooyinka Kululaynta

Iska caabin Oksaydh oo Wanaagsan NiCr 70/30 oo loogu talagalay fiilooyinka Kululaynta

Sharaxaad Gaaban:

NiCr 70/30 (2.4658) waa daawaha nikkel-chromium ee austenitic (daawaha NiCr) oo loo isticmaalo heerkulka ilaa 1250°C. Daawaha 70/30 waxaa lagu gartaa iska caabin sare iyo iska caabin oksaydh oo wanaagsan. Waxay leedahay dabacsanaan wanaagsan ka dib isticmaalka iyo alxan aad u fiican.


  • Darajada:NiCr 70/30
  • Cabbirka:waa la habeyn karaa
  • Qaab:Xarigga
  • Heerkulka ugu badan ee hawlgalka (°C):1250
  • Cufnaanta (g/cm³):8.1
  • Hantida Birlabta:aan ahayn

    NiCr 70/30 (2.4658) waxaa loo isticmaalaa kuleyliyaha korontada u adkaysta daxalka ee foornooyinka warshadaha leh jawi yareeya. Nikkel Chrome 70/30 aad ayuu u adkaystaa oksaydhka hawada. Laguma talinayo in loo isticmaalo walxaha kululaynta ee dahaarka leh ee MgO, ama isticmaalka iyadoo la adeegsanayo jawi nitrogen ama kaarboonaysan.
