Inconel 718 Siab -Kev Ua Haujlwm Kub
Ib qho ntawm cov yam ntxwv zoo kawg nkaus ntawm Inconel alloy 718 yog nws lub peev xwm los tswj lub zog ntawm qhov kub thiab txias.
Qhov siab tshaj plaws kev khiav hauj lwm kub: kwv yees li 650℃(1200℃F), zoo heev creep thiab kev nyuaj siab rupture tsis kam, thiab ruaj khov microstructure txawm tom qab ntev -lub sij hawm raug rau kub kub.
Yog li ntawd, alloy 718 yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov hauv qab no: cov khoom siv dav hlau dav hlau, cov roj turbine disks thiab cov ncej, siab -siab fasteners thiab springs.
Inconel 718 Corrosion Resistance thiab Oxidation Resistance
Inconel 718 muaj kev txhim khu kev qha nyob rau hauv ib puag ncig hnyav: nws tiv taus oxidation ntawm qhov kub txog li 980 degree, tiv taus pitting thiab crevice corrosion, thiab tiv taus acidic thiab alkaline txheej txheem xov xwm. Rau cov neeg siv khoom hauv kev lag luam roj thiab roj thiab tshuaj lom neeg, qhov no txhais tau tias kev pab cuam lub neej ntev dua thiab txo cov nqi kho.
Inconel 718 Weldability thiab Machinability
Tsis zoo li ntau lub siab -lub zog npib tsib xee alloys, Inconel 718 nthuav tawm zoo heev weldability: tsis tshua muaj kev pheej hmoo ntawm ncej-weld cracking, weldable nyob rau hauv cov tshuaj-annealed mob, thiab lub zog yuav rov qab los ntawm cov txheej txheem kev laus thaum tshav kub kub kho.Nws kuj yog haum rau: machining (yuav tsum tau tswj ceev, machining, thiab precision machining). Qhov kev pheej hmoo ntawm kev ua haujlwm qis dua txhais tau tias lub sij hawm luv luv thiab cov nqi kwv yees ntau dua.
Inconel 718 Cov yam ntxwv kho cua sov
Inconel 718 tau ntxiv dag zog los ntawm nag lossis daus hardening, tsis yog cov tshuaj muaj zog ntxiv.
Txheej txheem kev kho cua sov:
Kev daws annealing: kwv yees li 980 degree
Kev laus kev kho mob: 720℃→ 620℃(ob -kauj ruam)
Cov txheej txheem no tsim cov ″ theem, uas muab cov khoom siv nrog lub zog siab thiab zoo thermal stability.
Kev siv ntawm Inconel Alloy 718
Vim nws cov khoom sib npaug, Alloy 718 tau siv dav hauv:
Aerospace engine qhov chaw thiab cov khoom siv
Roj & Gas downhole cov cuab yeej thiab cov cuab yeej zoo
Nuclear reactor Cheebtsam
High - lub zog fasteners thiab springs
Siab -siab li qub thiab fittings
