Dab tsi yog qhov txawv ntawm inconel 750 thiab 718?
Dab tsi yog inconel 718?
Inconel 718 bar, 718 inconel almoy bar
Inconel 718 yog npib tsib xee-based superalloy paub rau nws lub zog siab, corrosion tsis kam, thiab zoo heev weldability. Nws yog nag lossis daus-hardenable, txhais tau nws cov khoom siv me me tuaj yeem txhim kho los ntawm kev kho cua sov.
Ntau yam: ua tau zoo hauv qhov kub thiab txias nyob rau -250 degree rau 700 degree.
Corrosion Kuj: Zoo heev tsis kam rau oxidation, pitting, thiab kev nyuaj siab-corrosion cracking, txawm nyob hauv ib puag ncig hnyav.
Neeg kho tshuab zog: High tensile thiab tawm lub zog vim nws cov ntsiab lus niobium.
Cov ntawv thov: feem ntau siv nyob rau hauv Aerospace turbines, roj turbines, nuclear reactors, thiab roj thiab roj tawm.
Dab tsi yog inconel x -750?
Inconel x -750 yog lwm cov neeg npib tsib xee uas zoo li cov neeg muaj txuj ci siab. Nws kuj tseem kub ntxhov-teeb meem tab sis muaj ntau aluminium thiab titanium tshaj inconel 718, pab txhawb rau nws lub zog ntawm kev kub siab.
Ntau yam: ua tau zoo nyob rau qhov kub thiab txias txog 980 degree.
Cramp Kuj: Zoo dua tsis kam rau deformation raws li kev ntxhov siab ntev-siab-kub.
Corrosion Kuj: Zoo ua rau oxidation thiab tshuaj lom neeg corrosion, txawm tias tsawg dua li inconel 718.
Cov ntawv thov: nquag siv nyob rau hauv lub dav hlau xyaw, nuclear reactors, springs, thiab fasteners.

Corrosion Kuj: Incmel 718 vs. Inconel x {1}}
Ob qho alloys muaj cov khoom tsis kam:
Inconel 718 Tiv thaiv pitting, thiab kev nyuaj siab corrosion, tshwj xeeb tshaj yog nyob rau hauv aqueous ib puag ncig. Nws yog qhov kev xaiv xaiv rau sab nrauv roj thiab roj app.
Inconel x -750} muaj oxidation zoo, tab sis nws txoj kev tiv taus tshuaj lom neeg ua haujlwm tsis zoo rau qhov tsis muaj 718.
Kev ua tau zoo hauv qhov chaw kub
Inconel 718:
Inconel 718 yog tsim rau cov ntawv thov nruab nrab- thiab siab-kub, tab sis pib poob cov khoom siv tau tshaj 700 degree. Nws weldability ua rau nws haum rau cov fabrication uas yuav tsum muaj qhov tseeb.
Inconel x -750:
Inconel x -750 tuaj yeem tiv taus kub txog 980 degree thiab muaj cov creep kuj zoo heev. Qhov no ua rau nws tsim nyog siv rau kev siv hauv cov khoom sib xyaw thiab nuclear reactor springs uas raug rau huab cua sov rau ncua sijhawm.
Cov ntawv thov ntawm inconel 718 thiab inconel x -750
Cov txiaj ntsig ntawm inconon 718
Zoo heev txhua yam muaj zog.
Zoo dua Weldability.
Zoo heev rau pitting thiab kev ntxhov siab corrosion tawg.
Cov txiaj ntsig ntawm inconel x -750
Zoo dua kev ua tau zoo.
Zoo heev creep kuj.
Qhov zoo tshaj plaws rau cov ntawv thov nthuav tawm qhov kub siab ntev ntev.
Nqi ntawm inconel 718 thiab inconel x -750
Inconel 718 feem ntau kim vim tias nws muaj ntau dua niobium thiab molybdenum, uas txhim kho nws lub zog thiab corrosion tsis kam. Ib qho ntxiv, nws cov kev ua haujlwm zoo dua hauv cov chaw hnyav thiab muaj kev xav tau, tshwj xeeb hauv cov roj thiab roj, aerospace, thiab sab nrauv engineering.
Inconel x -750 yog feem ntau pheej yig dua li inconel 718. Qhov no muaj ntau dua molybdenum) thiab cia li muaj ntau dua ntawm txhuas thiab titanium rau nag lossis daus. Nws tus nqi ntau lawm ua rau nws xaiv qhov kev xaiv kub nyiam rau qhov ntsuas kub siab qhov chaw uas cov tsis tseem ceeb.
