Kev Ua Tau Zoo Tshaj Plaws
Tshuaj muaj pes tsawg leeg
Kev ua tau zoo ntawm cov alloys no los ntawm lawv cov tshuaj pleev xim sib txawv. Txhua lub hauv paus ua lub luag haujlwm tshwj xeeb hauv cov khoom siv ua haujlwm li cas.
Inconel 625 muaj nickel siab -Chromium (Ni-Cr) puag nrog ntxiv Molybdenum (Mo) thiab Niobium (Nb). Cov ntsiab lus no sib xyaw rau hauv nickel-chrome matrix, ua rau cov khoom muaj zog thiab tiv taus corrosion ntau dua.
Inconel 718 kuj muaj Ni-Cr hauv paus tab sis muaj ntau yam hlau (Fe). Qhov sib txawv loj yog tias nws kuj muaj Titanium (Ti) thiab Aluminium (Al) nrog rau Niobium (Nb). Thaum kho cua sov, cov ntsiab lus no tsim cov khoom tawv tawv me me. Yog xav paub ntxiv, xyuas cov ncauj lus kom ntxaws txog cov tshuaj muaj pes tsawg leeg.
Mechanical Strength
Qhov sib txawv loj tshaj ntawm Inconel 625 vs 718 yog lawv muaj zog npaum li cas. Qhov no los ntawm qhov lawv muaj zog.
Thaum tshav kub kub-kho, Inconel 718 muaj zog ntau dua thiab nyuaj dua Inconel 625. Nws nyob ruaj khov ntawm chav tsev kub txog li 650-700℃(1200-1300℃F).
Lub zog no yog los ntawm cov khoom me me, nyuaj uas tsim hauv cov khoom siv thaum kho cua sov. Cov khoom no thaiv kev txav mus los hauv cov hlau, ua rau nws tiv taus kev khoov lossis tawg hauv siab.
Inconel 625 tau txais nws lub zog sib txawv thiab tsis muaj zog li 718 hauv qhov kub thiab txias. Tab sis 625 khaws nws lub zog zoo dua 700 degree. Ntawm qhov kub siab dua no, nws feem ntau siv qhov twg corrosion kuj tseem ceeb tshaj lub zog.
Corrosion Resistance
Qhov no yog qhov twg Inconel 625 tiag tiag ci. Nws cov chemistry tshwj xeeb yog tsim los sawv ntsug rau qhov chaw hnyav.
Qhov siab ntawm chromium thiab molybdenum hauv Inconel 625 muab kev tiv thaiv zoo heev tiv thaiv ntau hom kev xeb. Nws tiv thaiv ob qho tib si corrosion thiab tsom tawm tsam zoo li pitting, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntsev xws li dej hiav txwv.
