Dab tsi yog qhov txawv ntawm Monel K500 thiab Inconel 718 alloys?
Dab tsi yog qhov txawv ntawm Monel K500 thiab Inconel 718 alloys?
Monel K500 alloy (nickel{1}}tooj liab alloy) ua tau zoo nyob rau hauv marine / seawater corrosion kuj thiab ductility ntawm nruab nrab kub, thaum Inconel 718 (nickel-chromium-} hlau alloy)) boasts tshwj xeeb lub zog thiab siab - kub kev ua tau zoo (txog li 20 feeb ntawm lub cav), nws tsim nyog rau kev siv dav hlau 22. Yog li ntawd, Inconel yog qhov zoo dua rau cov huab cua siab heev - kub / siab - kev ntxhov siab ib puag ncig, thaum Monel yog qhov tsim nyog rau cov dej hiav txwv hnyav / acidic qhov chaw uas muaj zog siab tsis yog qhov tseem ceeb rau kev xav. K500 alloy ua tiav lub zog los ntawm lub hnub nyoog hardening, tab sis raug txwv los ntawm qhov kub thiab txias, thaum lub complex muaj pes tsawg leeg ntawm Inconel 718 tso cai rau nws tswj cov khoom zoo heev txawm nyob rau hauv huab cua kub.
Puas yog Monel K500 sib nqus?
Vim nws lub zog siab thiab qis corrosion nyob rau hauv siab -ceev seawater, nws yog tshwj xeeb tshaj yog haum rau centrifugal twj nyob rau hauv lub marine kev lag luam. MONEL K500 tsis yog -magnetic. MONEL K500 yuav tsum tau muab tshem tawm thaum lub sij hawm vuam, kev ntxhov siab-tso siab tom qab vuam, thiab tom qab ntawd muaj hnub nyoog- tawv.
