♦Qalabka: Inconel 718
♦A halkii macaamiishu sawir
♦Codsiga:nidaamka dhamaystirka ceelka saliidda iyo gaaska iyo habka loo rakibo isku mid
♦Waxaan soo saareynaa oo aan bixinaa tuubada saliidda sida waafaqsan sawirka macaamiisha, alaabtayada ugu muhiimsan waa Inconel 718, Inconel 725, Monel 400 iyo Inconel x750, Waxay ka samaysan yihiin bar foriging oo leh xaalad kuleyl, Cabbir iyo dulqaad sida macaamiisha sawiraan.
Inconel® 718waa dabeylaha nikkel-chromium-ka roobka adkeeya oo leh awood sare iyo ductility wanaagsan ilaa 1300°F (704°C).Alloy ka kooban xaddi la taaban karo oo bir, kolumbium, iyo molybdenum, oo ay la socdaan xaddi yar oo aluminium iyo titanium.Nickel 718 waxa kale oo uu leeyahay xad wanaagsan weldability, formability, iyo sifooyin cryogenic aad u fiican marka la barbar dhigo roobab kale adkaynaya Alloys nikkel.Jawaabta adkeyd ee roobka da'aya ee alloy-kan waxa ay u ogolaataa in si diyaar ah loo alxankaro iyada oo aan la adkayn ama dillaacin.Alloy 718 waa non-magnetic.Waxay ilaalisaa iska caabbinta daxalka wanaagsan iyo iska caabinta oksaydheynta waxaana loo isticmaalaa qaybaha u baahan iska caabin sare u qaadida gurguurta iyo dilaaca diiqada ilaa 1300°F (704°C) iyo iska caabinta oksaydhka ilaa 1800°F (982°C).

Inconel 718 waa qaab-dhismeedka Austenitic, adkeynta roobabku waxay abuuraan "γ" waxay ka dhigtay waxqabad farsamo oo heer sare ah.Xadka roobka G waxa uu dhaliyaa “δ” waxa uu ka dhigay caagagga ugu fiican daawaynta kulaylka
1.shaqayn
2.High adkaysiga xoogga, xoog dulqaadashada, xoog gurguurta iyo xoog dilaac at 700 ℃.
3.Inoxidability sare at1000 ℃.
4.Waxqabadka farsamada ee joogtada ah ee heerkulka hooseeya.
Heerkulka sare ee xoogga, caabbinta daxalka aad u fiican iyo karti-shaqsiyeedka guryaha 700 ℃ waxay ka dhigtay inay u isticmaasho deegaan baahi badan oo kala duwan.Heerarka inconel waxay ku habboon yihiin in loo isticmaalo soo saarista qaybaha ka shaqeeya jawiga daran sida turbocharger rotors & seals, matoorrada matoorada loogu talagalay bamka ceelka korantada ee korantada, matoorrada uumiga, tuubooyinka kulaylka beddelayaasha, qalabka wax lagu xakameeyo dhawaaqa dabka iyo qoryaha mishiinka. , rikoodhada sanduuqa madow ee diyaaradaha iwm.
