Muaj qhov sib txawv tseem ceeb ntawm Inconel 600 thiab Inconel 718 hauv ntau yam, suav nrog tshuaj lom neeg muaj pes tsawg leeg, kev tiv thaiv corrosion, kev ua haujlwm kub, kev siv tshuab thiab cov chaw siv. Cov hauv qab no yog cov ncauj lus kom ntxaws sib piv:
1. Tshuaj muaj pes tsawg leeg
Inconel 600: Cov khoom tseem ceeb yog npib tsib xee (li 72%), chromium (14-17%), hlau (6-10%) thiab tooj liab (0.5%), thiab kuj muaj me me. Molybdenum, manganese, silicon thiab carbon. Lub siab nickel cov ntsiab lus ntawm cov hlau no ua rau nws muaj qhov kub thiab txias corrosion kuj.
Inconel 718: Cov ntsiab lus npib tsib xee hauv cov hlau yog li ntawm 52-55%, thiab nws kuj muaj cov chromium siab (19-22%), niobium (4.75-5.5%), titanium ({ {6}}%) thiab txhuas (0.65-1.15%). Qhov sib ntxiv ntawm cov ntsiab lus no ua rau 718 alloy muaj kev ua tau zoo dua nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig.
2. Corrosion kuj
Nickel-raws li alloy 600: Nws muaj kev tiv thaiv zoo rau ntau yam corrosive media, nrog rau cov kua qaub, alkalis thiab oxidants. Nws yog qhov tshwj xeeb tshaj yog haum rau cov cheeb tsam uas muaj cov tshuaj chloride ions, nrog rau cov tshuaj chloride thiab cov tshuaj caustic uas muaj OH.
Nickel-based alloy 718: Nws kuj muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem ua tau zoo hauv cov xov xwm corrosive xws li acids, alkalis, thiab chlorides. Tsis tas li ntawd, 718 alloy kuj qhia tau hais tias zoo tiv thaiv pitting, crevice corrosion thiab kev nyuaj siab corrosion nyob rau hauv nruab nrab chloride ion media.
3. Kev ua haujlwm siab kub
Nickel-raws li alloy 600: Nws tuaj yeem tswj kev ruaj ntseg zoo thiab corrosion kuj nyob rau hauv qhov kub thiab txias, tab sis nws qhov siab tshaj plaws kev khiav hauj lwm kub feem ntau tsis tshaj 1100.
Nickel-based alloy 718: Nws muaj lub zog kub zoo heev thiab tuaj yeem tswj tau lub zog siab thiab tawv txawm nyob rau qhov kub thiab txias. Nws qhov kub siab tshaj plaws tiv thaiv kub tuaj yeem ncav cuag li 704C, uas ua rau nws siv tau ntau dua hauv cov ntawv thov kub kub.
4. Mechanical zog
Nickel-based alloy 600: Nws muaj cov khoom siv zoo, nrog rau lub zog siab thiab hardness, nrog rau kev ua haujlwm zoo. Txawm li cas los xij, nws lub zog siv tshuab yuav raug txwv nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig.
Nickel-raws li alloy 718: Tom qab kev kho cua sov thiab txias kos duab hardening, 718 alloy muaj lub zog siab thiab qee qhov yooj thiab plasticity. Nyob rau tib lub sijhawm, nws kuj muaj lub neej qaug zog zoo heev thiab kev ua haujlwm vuam zoo.
5. Daim ntawv thov teb
Nickel-based alloy 600: Siv dav hauv kev lag luam tshuaj, roj av thiab nuclear, tshwj xeeb tshaj yog tsim rau cov khoom siv thiab cov khoom siv hauv qhov kub thiab txias, xws li cov cua sov, cov khoom siv hluav taws xob, cov reactors thiab cov kav dej. Tsis tas li ntawd, nws kuj tau siv dav hauv kev tsim cov khoom siv roj thiab cov khoom siv rau cov tshuab hluav taws xob nuclear.
Nickel-raws li alloy 718: Vim nws zoo heev kub lub zog, corrosion kuj thiab toughness, nws yog dav siv nyob rau hauv high kub, siab siab thiab corrosive ib puag ncig nyob rau hauv aerospace, shipbuilding, petrochemical thiab lwm yam teb, xws li turbine hniav, roj turbines, aircraft cav, roj laum khoom, thiab lwm yam.
