1. Inconel 718 yog dab tsi thiab nws cov yam ntxwv tseem ceeb?
Teb:
Inconel 718 (UNS N07718, W. Nr. 2.4668) yog nickel-raws li superalloy paub txog nws lub zog tshwj xeeb, tiv thaiv corrosion, thiab kev ua haujlwm ntawm qhov kub thiab txias. Nws tuav nws cov cuab yeej cuab tam mus txog li 700℃(1,292℃F), thiab nthuav tawm kev nkag siab zoo thiab qaug zog. Nws tseem yog weldable thiab tuaj yeem tsim ua ntau yam duab, ua rau nws zoo tagnrho rau kev siv aerospace, tshuaj, thiab hluav taws xob tsim hluav taws xob.
2. Dab tsi yog cov kev siv ntawm Inconel 718 round bars/rods?
Teb:
Inconel 718 round bars / rods yog siv dav hauv kev lag luam uas muaj zog thiab siab - qhov kub thiab txias yuav tsum tau ua:
Aerospace Cheebtsam xws li turbine hniav, discs, thiab shafts
Rocket thiab dav hlau cav qhov chaw
High -cov khoom siv tshuaj ua haujlwm kub
Nuclear reactor Cheebtsam
High -kev ua tau zoo li qub, fasteners, thiab fittings
3. Dab tsi yog cov khoom siv kho tshuab ntawm Inconel 718 round bars?
Teb:
Cov cuab yeej cuab tam ntawm Inconel 718 puag ncig tuav suav nrog:
Tensile zog: ~ 1,270 MPa (185,000 psi)
Tawm Zog: ~ 1,100 MPa (160,000 psi)
Ntev: ~ 20-25%
Hardness: ~ 35-42 HRC
Cov khoom no tso cai rau nws tiv taus cov neeg kho tshuab huab cua thiab thermal stresss dhau lub sijhawm ntev.
4. Dab tsi ua rau Inconel 718 haum rau siab -kub thiab corrosive ib puag ncig?
Teb:
Inconel 718 muaj kev tiv thaiv zoo rau:
Oxidation thiab scaling ntawm qhov kub thiab txias
Corrosion los ntawm acids thiab seawater
Kev nyuaj siab corrosion cracking nyob rau hauv hnyav tshuaj ib puag ncig
Nws cov ntsiab lus nickel thiab chromium siab, ua ke nrog kev ntxiv ntawm molybdenum thiab niobium, ua kom muaj kev ruaj ntseg thiab lub zog hauv cov xwm txheej nyuaj, ua rau nws muaj kev ntseeg siab rau cov ntawv thov tseem ceeb.
5. Dab tsi cov qauv thiab specifications siv rau Inconel 718 round bars/rods?
Teb:
Inconel 718 round bars / rods yog tsim los ua kom tau raws li cov qauv thoob ntiaj teb xws li:
ASTM B637 / B670 - Nickel thiab Nickel Alloy Forgings thiab Bars
AMS 5663 / AMS 5662 - Aerospace khoom specifications
UNS N07718 / W. Nr. 2.4668 – Alloy designation for nickel-raws li superalloy
Cov qauv no xyuas kom meej tias cov kab puag ncig / pas nrig ua tau raws li qhov yuav tsum tau ua rau cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov ntev ntev.
