2.4668 Inconel 718 yog nickel-chromium-molybdenum high-temperature alloy, uas kuj suav nrog Fe, Nb, Ti, Al, Cb, Ta, thiab lwm yam. .
1. Nickel (50-55%) : Cov ntsiab lus nickel siab ua rau muaj kev tiv thaiv corrosion zoo heev ntawm Inconel 718, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav thiab kub.
2. Chromium (17-21 feem pua): Chromium txhim kho oxidation tsis kam thiab kub-siab zog. Nws kuj tseem pab cov Inconel 2.4668 tsim cov txheej txheem oxide tiv thaiv, uas ua rau nws cov corrosion kuj.
3. Hlau (17-21 feem pua): Hlau yog lub ntsiab tseem ceeb cuam tshuam rau lub zog, toughness, thiab lwm yam khoom ntawm 2.4668 Inconel 718.
4. Niobium (4.75-5.5 feem pua): Niobium, tseem hu ua columbium, muab kev ruaj ntseg thiab nag lossis daus hardening. Nws pab txhawb rau lub siab kub lub zog thiab theem stability ntawm lub alloy.
5. Molybdenum (2.8-3.3 feem pua : Molybdenum txhim khu kev tiv thaiv corrosion ntawm 2.4668 alloys 718 nyob rau hauv ntau qhov chaw (xws li acids thiab chlorides). Nws kuj pab tswj lub zog ntawm qhov kub thiab txias.
6. Titanium (0.65-1.15 feem pua : Titanium pab2.4668 Inconel 718teb rau nag lossis daus hardening, yog li txhim kho nws lub zog thiab kev ua haujlwm ntawm qhov kub thiab txias.
7. Aluminium (0.2-0.8 feem pua : Aluminium yog lwm yam khoom uas ua rau nag lossis daus hardening. Nws ua ke nrog titanium los tsim kom muaj zog precipitates thaum kho cua sov.
8. Columbium ntxiv rau Tantalum (0.7-1.2 feem pua : Cov ntsiab lus no ua rau cov qoob loo ntxiv dag zog thiab theem kev ruaj ntseg, tshwj xeeb tshaj yog thaum kub kub.
