Dab tsi yog qhov txawv ntawm 925 alloy thiab 718 alloy?
Dab tsi yog qhov txawv ntawm 925 alloy thiab 718 alloy?
The main difference lies in their chemical composition. Alloy 718 has a higher nickel content (>50%), thaum Alloy 925 muaj cov ntsiab lus nickel qis (38-46%) tab sis cov ntsiab lus hlau ntau dua. Qhov no ua rau Alloy 925 ib qho kev siv nyiaj ntau dua thaum muab lub zog sib piv, tshwj xeeb tshaj yog haum rau kev siv roj thiab roj, thiab muab kev tiv thaiv zoo dua rau sulfide kev ntxhov siab tawg thiab pitting hauv acidic ib puag ncig. Alloy 718 yog lub npe nrov rau nws lub zog siab tshaj qhov kub thiab txias thiab siv dav hauv kev lag luam aerospace.
Dab tsi yog lwm txoj hauv kev rau Inconel 718?
Inconel 718 yog ib qho tshwj xeeb nickel-raws li alloy, yog li tsis muaj qhov sib npaug ncaj qha. Txawm li cas los xij, ob peb lwm cov nickel-raws li alloys muaj cov khoom zoo sib xws thiab tuaj yeem ua lwm txoj hauv kev siv qee yam. Qee qhov ntawm cov hlau no suav nrog Rene 41.
Thaum xaiv cov ntaub ntawv rau siab -kev ua tau zoo, alloys 925 thiab 718 yog ob hom nickel-raws li alloys. Txawm hais tias ob qho tib si muaj lub zog zoo, kev tiv thaiv corrosion, thiab kav ntev, lawv tau tsim los rau ntau lub hom phiaj, thiab lawv cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev siv sib txawv. Kab lus no yuav tshawb txog qhov sib txawv tseem ceeb ntawm ob lub alloys no.
