Qhov Zoo ntawm Monel yog dab tsi?
Monel alloy muaj qhov zoo thiab cov txiaj ntsig hauv qab no:
Kev sib xyaw ua ke ntawm lub zog siab thiab zoo heev corrosion kuj. Nws muaj qhov zoo corrosion kuj nyob rau hauv ib puag ncig sib txawv. Qhov no suav nrog kev tiv thaiv acids, alkalis, thiab dej tshiab thiab ntsev raug. Nws cov kev tiv thaiv corrosion tshaj li ntawm lwm cov hlau uas muaj corrosion-resistant xws li 316 stainless hlau.
Monel alloys, tshwj xeeb yog Monel 400, muaj cov txiaj ntsig siab dua thiab tensile zog dua li 316 stainless hlau.
Monel alloys muaj qis coefficient ntawm thermal expansion piv rau austenitic stainless hlau. Qhov no yog qhov txiaj ntsig tseem ceeb rau cov ntawv thov uas qhov kev ruaj ntseg ntawm qhov sib txawv ntawm qhov kub thiab txias yog qhov tseem ceeb.
Yuav tau yooj yim welded, soldered thiab brazed.
Ua tau zoo nyob rau hauv ob qho tib si qis thiab kub daim ntawv thov. Nws tuav nws lub zog nyob rau hauv qhov kub thiab txias ntawm subzero mus rau 480 degree.
Monel alloy yog non-magnetic thiab muaj Curie point tsawg heev.
Ib qho txiaj ntsig tseem ceeb ntawm wrought npib tsib xee-raws li alloys, paub txog lawv cov kev tiv thaiv corrosion, yog lawv lub peev xwm tiv taus chloride-induced stress corrosion cracking (SCC). Hom corrosion no yog ib qho teeb meem tshwm sim nrog stainless hlau. Interestingly, nws tau pom tias qhov kev nyuaj siab corrosion cracking kuj ntawm cov nickel alloys txo nrog nce hlau cov ntsiab lus. Qhov no txhais tau hais tias cov nickel alloys nrog cov ntsiab lus ntawm cov hlau qis dua yog qhov ua tau zoo ntawm kev tiv thaiv qhov tshwj xeeb ntawm kev puas tsuaj ntawm corrosion. Txawm li cas los xij, ob qho tib si Monel K-500 thiab Alloy 400 muaj kev cuam tshuam rau kev ntxhov siab corrosion cracking, tab sis lawv tseem feem ntau suav hais tias zoo tshaj rau austenitic stainless hlau hauv qhov no.
