Inconel® 718 yog cov nag lossis daus-tawv tawv nickel-chromium alloy nrog ib qhosiab zog thiab zoo ductility mus txog 1300 ° F (704 ° C).Cov Alloy no muaj cov khoom tseem ceeb ntawm cov hlau, columbium, thiab molybdenum, nrog rau tsawg dua ntawm txhuas thiab titanium.Nickel 718 kuj muaj qhov zoo weldability, formability, thiab zoo heev cryogenic zog piv rau lwm cov nag lossis daus hardening nickel alloys.Lub sluggish nag lossis daus hardening teb ntawm no alloy tso cai rau nws tau yooj yim welded tsis hardening los yog cracking.Alloy 718 tsis yog hlau nplaum.Nws tuav tau zoo corrosion kuj thiab oxidation tsis kam thiab yog siv rau qhov chaw uas yuav tsum tau muaj siab tsis kam mus creep thiab kev nyuaj siab rupture mus txog 1300 ° F (704 ° C) thiab oxidation kuj mus txog 1800 ° F (982 ° C).

Inconel 718 yog Austenitic qauv, nag lossis daus hardening tsim "γ" ua rau nws zoo heev mechanical kev ua tau zoo.G los nag ciam teb tsim "δ" ua nws qhov zoo tshaj plaws plasticity nyob rau hauv kev kho cua sov.with tsis tshua muaj zog tiv thaiv corrosion cracking thiab pitting peev xwm nyob rau hauv kub los yog tsis kub qhov chaw, tshwj xeeb tshaj yog cov inoxidability nyob rau hauv lub siab kub.
1. kev ua haujlwm
2.High tensile zog, endurance zog, creep zog thiab rupture zog ntawm 700 ℃.
3.High inoxidability ntawm 1000 ℃.
4.Steady mechanical kev ua tau zoo nyob rau hauv qhov kub thiab txias.
Lub siab kub lub zog, zoo heev corrosion kuj thiab workability ntawm 700 ℃ khoom ua rau nws siv nyob rau hauv ib tug ntau yam ntawm siab xav tau ib puag ncig.Cov qib Inconel yog haum rau siv nyob rau hauv zus tau tej cov Cheebtsam uas ua hauj lwm nyob rau hauv ib tug hnyav ib puag ncig xws li turbocharger rotors & seals, lub cev muaj zog shafts rau hluav taws xob submersible zoo twj tso kua mis, chav generators, raj rau tshav kub exchangers, phom suab suppressor blast baffles thiab nyob rau hauv lub tshuab phom , black box recorders nyob rau hauv dav hlau thiab lwm yam.
