1. Cov tshuaj muaj pes tsawg leeg ntawm Inconel 783 (UNS N07783) yog dab tsi?
Teb:
Nickel (Ni): 57% min
Chromium (Cr): 17-21%
Cobalt (CO): 8-12%
Molybdenum (Mo): 1-2%
Hlau (Fe): 4-10%
Cov ntsiab lus me: Cov pa roj carbon tsawg dua lossis sib npaug li 0.10%, Manganese Tsawg dua lossis sib npaug 0.35%, Silicon Tsawg dua lossis sib npaug rau 0.25%, Titanium 2.0-3.0%
Cov hlau no muab lub zog siab thiab zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv marine thiab siab -kub ib puag ncig.
2. Lub raj no ua raws li cov qauv dab tsi, thiab vim li cas lawv tseem ceeb?
Teb:
ASTM B446: Npog nickel thiab cobalt alloy tubes, kom ntseeg tau qhov tseeb qhov tseeb, txhua yam khoom siv, thiab kev tiv thaiv corrosion.
AMS 5940: Aerospace tus qauv qhia cov tshuaj muaj pes tsawg leeg, kev kho cua sov, thiab cov khoom siv tshuab.
Kev ua raws cai ua kom muaj kev ntseeg siab rau kev tsim vaj tsev hauv hiav txwv thiab kev ua haujlwm siab - daim ntawv thov.
3. Dab tsi yog cov khoom siv kho tshuab ntawm Inconel 783 raj?
Teb (tus qauv, kev daws teeb meem-annealed):
Tensile zog: 1100-1300 MPa
Tawm Zog: 950-1050 MPa
Elongation: 15-25%
Hardness (Rockwell C): 35-40
Kev nkag siab zoo heev thiab kev ntxhov siab- tawg tsis kam ntawm qhov kub txog li 700℃.
4. Vim li cas Inconel 783 thiaj li tsim nyog rau kev siv marine engineering?
Teb:
Resistant rau seawater corrosion thiab ntsev tsuag ib puag ncig
Tuav lub zog txhua yam nyob rau hauv cyclic thiab siab - qhov kub thiab txias
Resistant oxidation, kev nyuaj siab corrosion cracking, thiab thermal qaug zog, kom ntseeg tau ntev -lub sij hawm cia siab rau hauv marine khoom
5. Dab tsi yog cov kev siv ntawm UNS N07783 raj?
Teb:
Marine tso pa thiab turbine Cheebtsam
Thaum tshav kub kub exchangers thiab boiler raj
Aerospace cav thiab roj turbine Cheebtsam
Cov cuab yeej siv tshuaj lom neeg nyob rau hauv siab -kub thiab corrosive ib puag ncig
Nws ua ke ntawm lub zog, kub stability, thiab corrosion kuj ua rau nws zoo tagnrho rau hnyav marine thiab industrial tej yam kev mob.
