Chithunzi cha GH4169
1. Kufotokozera:
GH4169 ndi mvula yolimbitsa mvula yomwe imatetezedwa ndi kutentha kwapamwamba komanso ntchito yabwino yokwanira kutentha.
osiyanasiyana -253 650C m'nyumba.
Mphamvu zokolola zosakwana 650C zimakhala zoyamba pakati pa ma aloyi opunduka omwe amatentha kwambiri, ndipo ali ndi kukana kutopa, kukana kutentha,
kukana ma oxidation, corrosion resistance, komanso kukonza bwino ndi kuwotcherera.
2. Mlingo wofanana:
Inconel 718, UNS NO7718 (USA), NCI9FeNb (France), W. Nr. 2.4668 (Germany)

5. Katundu Wabwino:
1) Kutentha kwakukulu kwamphamvu: GH4169 aloyi yotentha kwambiri imakhala ndi mphamvu yotentha kwambiri, imatha kugwira ntchito kwa nthawi yayitali
malo otentha kwambiri, ndipo ali ndi kukana kutopa kwambiri.
2) Kukana kwa dzimbiri: GH4169 aloyi yotentha kwambiri imakhala ndi kukana kwa dzimbiri ndipo imatha kupirira asidi amphamvu, alkali, komanso kutentha kwambiri.
malo okosijeni
3) Machinability: GH4169 mkulu-kutentha aloyi ali machinability wabwino ndipo angagwiritsidwe ntchito forging, kutentha mankhwala, kuwotcherera ndi njira zina processing.
6. Kugwiritsa ntchito:
GH4169 high-temperature alloy imagwiritsidwa ntchito kwambiri muzamlengalenga, mphamvu, ndi mankhwala, monga masamba a injini yandege, mbali zachipinda choyaka moto, zida zamafuta amagetsi a nyukiliya, etc.
