Inconel® 718 ndi aloyi wowumitsa mvula wa nickel-chromium wokhala ndimphamvu zazikulu ndi ductility wabwino mpaka 1300 ° F (704 ° C).Aloyi iyi yomwe ili ndi chitsulo chochuluka, columbium, ndi molybdenum, pamodzi ndi aluminium ndi titaniyamu yocheperapo.Kuwumitsa kwamvula kwanthawi yayitali kwa aloyiyi kumapangitsa kuti azitha kuwotcherera mosavuta popanda kuumitsa kapena kusweka.Aloyi 718 si maginito.Imasunga kukana kwa dzimbiri komanso kukana kwa okosijeni ndipo imagwiritsidwa ntchito pazigawo zomwe zimafuna kukana kwambiri kukwawa ndi kusweka kwa nkhawa mpaka 1300 ° F (704 ° C) ndi kukana kwa okosijeni mpaka 1800 ° F (982 ° C).

Inconel 718 ndi mawonekedwe a Austenitic, kuuma kwa mvula kumapanga "γ" kunapangitsa kuti ikhale yabwino kwambiri pamakina.G mvula malire kupanga "δ" anaupanga kukhala pulasitiki yabwino kwambiri kutentha treatment.with kwambiri kukana kupsinjika dzimbiri akulimbana ndi pitting mphamvu mu kutentha kwambiri kapena malo otsika kutentha, makamaka inoxidability mu kutentha kwambiri.
1.ntchito
2.Mkulu wamakokedwe mphamvu, kupirira mphamvu, kukwawa mphamvu ndi kuphulika mphamvu pa 700 ℃.
3. High inoxidability pa 1000 ℃.
4.Steady makina ntchito mu kutentha otsika.
Kutentha kwamphamvu kwamphamvu, kukana kwa dzimbiri komanso kugwira ntchito kwa 700 ℃ kunapangitsa kuti igwiritsidwe ntchito m'malo osiyanasiyana ofunikira kwambiri.Magiredi a Inconel ndi oyenera kugwiritsidwa ntchito popanga zida zomwe zimagwiritsidwa ntchito m'malo ovuta kwambiri monga ma turbocharger rotor & seals, shafts motor shafts yamagetsi opangira chitsime chamagetsi, ma jenereta a nthunzi, machubu osinthira kutentha, maphokoso amfuti amawombera komanso mfuti zamakina. , zojambulira za black box mu ndege etc.
