Tete'e Lelei i le Oxidation NiCr 70/30 mo Uaea Fa'avevela

Fa'amatalaga Pupuu:

O le NiCr 70/30 (2.4658) o se austenitic nickel-chromium alloy (NiCr alloy) mo le faʻaaogaina i le vevela e oʻo atu i le 1250°C. O le 70/30 alloy e iloga i le maualuga o le teteʻe ma le lelei o le teteʻe atu i le oxidation. E lelei lona ductility pe a uma ona faʻaaogaina ma e sili ona lelei le weldability.

    E fa'aaogaina le NiCr 70/30 (2.4658) mo elemene fa'avevela eletise e tete'e atu i le 'ele i ogaumu fa'apisinisi ma le ea e fa'aitiitia ai le vevela. E matua tete'e lava le Nickel Chrome 70/30 i le 'okesene i le ea. E le fautuaina mo le fa'aaogaina i elemene fa'avevela ua ufiufi i le MgO, po'o fa'aoga e fa'aaogaina ai le nitrogen po'o le ea e fa'acarburize ai.
