Produkt FEATURE
GH738 is in nikkel-basearre hege-temperatuer alloy ferhurde troch γ' faze delslach, mei goede gas corrosie ferset, hege opbringst sterkte en wurgens eigenskippen, goede proses plasticity en stabile organisaasje. In soad brûkt yn fleantúchmotor rotearjende dielen, it brûken fan temperatuer is net heger as 815 ℃. It kin produsearje kâld rôle en hjit rôle platen, pipen, strips, triedden, forgings, castings en fasteners.
Produkt applikaasje
Fleantúchmotoren, masinegasturbines, turbineblêden en turbineskiven en oare draaiende dielen.
