Inconel 718 yog lub zog siab, corrosion-resistant nickel-raws li alloy dav siv nyob rau hauv high-temperature thiab high-pressure ib puag ncig xws li aerospace thiab petrochemicals.
Mechanical zog
Inconel 718 muaj cov cuab yeej zoo heev, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub kub, nws tuaj yeem tswj tau lub zog thiab ruaj khov.
Nws cov kev ua tau tseem ceeb yog raws li hauv qab no:
Yield zog: Nyob rau hauv chav tsev kub, lub zog tawm los ntawm Inconel718 yog hais txog 1030MPa, thiab nws tseem muaj peev xwm tuav tau ib tug yield zog ntawm txog 500MPa ntawm 650 degree.
Lub zog tensile: lub zog tensile ntawm chav tsev kub tuaj yeem ncav cuag 1400MPA, thiab ntawm 600 degree tseem tuaj yeem tswj hwm sab saud 900mpa.
Ductility: Inconel 718 muaj qhov zoo ductility, thiab elongation tom qab tawg ntawm chav tsev kub yog li 15%, qhia tias cov hlau tseem khaws cov yas zoo ntawm qhov kub thiab txias.
Lub creep tsis kam ntawm Inconel718 yog qhov zoo heev ntawm qhov kub thiab txias, thiab nws qhov nkag siab ntawm 650 degree qis, uas yog tsim rau cov ntawv thov uas raug kub siab rau lub sijhawm ntev.
Cov xwm txheej muab khoom
Cov txheej txheem ntawm Inconel 718 alloy feem ntau suav nrog kub dov, txias dov, casting thiab forging, uas tsim nyog rau kev ua haujlwm sib txawv.
Cov xwm txheej kub: Inconel718 feem ntau yog muab nrog kev kho mob laus (720-740 degree) tom qab daws teeb meem). Txoj kev kho cua sov no pab txhawm rau txhim kho lub zog thiab corrosion tsis kam ntawm cov alloy.
Daim ntawv ua haujlwm: Cov ntaub ntawv muab khoom siv feem ntau suav nrog cov phaj, tuav, kav dej thiab castings kom tau raws li cov txheej txheem sib txawv.
Cov kev kho deg: lub alloy feem ntau pickled lossis kho txheej txheem polished kom tshem tawm cov txheej oxide thiab txhim kho nws cov khoom zoo.
