Monel K400 thiab K500 yog ob tug tswv cuab ntawm tsev neeg Monel alloy nto moo, tab sis lawv muaj cov yam ntxwv sib txawv uas ua rau lawv sib txawv, ua rau txhua tus haum rau ntau daim ntawv thov. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau cov engineers, cov chaw tsim khoom, thiab cov neeg nyiam cov khoom siv uas tab tom nrhiav kev txiav txim siab xaiv cov khoom siv.

Qhov sib txawv tseem ceeb tshaj plaws yog nyob rau hauv lawv cov tshuaj lom neeg muaj pes tsawg leeg.MonelK400 feem ntau yog tsim los ntawm nickel (kwv yees li 63%) thiab tooj liab (28%), nrog rau me me ntawm hlau thiab manganese. Cov khoom sib xyaw ua ke no yooj yim tab sis ua tau zoo pab txhawb rau nws txoj kev tiv thaiv corrosion zoo heev thiab cov khoom siv kho tshuab zoo ntawm chav tsev kub. Qhov sib piv, Monel K500 tsim rau ntawm lub hauv paus ntawm K400 los ntawm kev ntxiv txhuas thiab titanium. Cov ntsiab lus ntxiv no ua rau K500 dhau los ua cov txheej txheem ua kom tawv, uas ua rau nws lub zog thiab tawv dua piv rau K400.

Qhov sib txawv ntawm cov khoom no cuam tshuam ncaj qha rau lawv cov khoom siv kho tshuab. Monel K400 muaj cov ductility zoo thiab formability, ua rau nws yooj yim rau fabricate rau hauv ntau yam duab. Nws muaj lub zog tensile qis dua, uas yog tsim rau cov ntawv thov qhov twg yooj ywm thiab yooj yim ntawm machining yog qhov tseem ceeb, xws li hauv kev tsim cov kav dej hiav txwv thiab cov khoom siv tiv thaiv corrosion dav dav. Monel K500, tom qab nag los ua kom tawv, qhia tau tias muaj zog tensile thiab cov txiaj ntsig zoo dua. Nws tuaj yeem tiv taus kev ntxhov siab ntau dua, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau cov khoom muaj zog, xws li cov twj tso kua mis, cov kav dej, thiab cov fasteners hauv cov tshuab hnyav thiab cov nkoj marine.

Kev tiv thaiv corrosion yog lwm qhov chaw uas ob qho alloys qhia qhov sib txawv. Ob qho tib si Monel K400 thiabK500muab kev tiv thaiv zoo heev rau ntau yam corrosive media, suav nrog dej hiav txwv, cov kua qaub me me, thiab alkalis. Txawm li cas los xij, vim nws lub zog siab dua thiab kev tsim cov txheej txheem oxide tiv thaiv ruaj khov dua thaum lub sijhawm ua kom tawv tawv, Monel K500 feem ntau qhia txog kev tiv thaiv zoo dua rau kev ntxhov siab corrosion cracking, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj cov chloride ntau. Qhov no ua rau K500 yog qhov kev xaiv zoo rau cov khoom uas tsis yog tsuas yog raug rau cov khoom corrosive tab sis kuj xav tau kev nyuaj siab tib lub sijhawm.

Hais txog daim ntawv thov, Monel K400 feem ntau siv rau hauv kev lag luam marine rau cov khoom xws li condensers, heat exchangers, thiab seawater piping, qhov twg nws cov corrosion tsis kam thiab formability yog qhov tseem ceeb. Nws kuj tseem siv rau hauv kev lag luam tshuaj rau kev tswj cov tshuaj tsis-aggressive. Monel K500, ntawm qhov tod tes, yog siv rau hauv cov ntawv thov uas xav tau ntau dua. Hauv cov roj thiab roj av, nws yog siv rau cov cuab yeej downhole thiab cov khoom siv subsea, qhov twg lub zog siab thiab corrosion tsis kam yog qhov tseem ceeb. Hauv kev lag luam aerospace, K500 Cheebtsam tuaj yeem pom hauv cov khoom uas xav tau ob qho tib si lub zog thiab kev tiv thaiv rau ib puag ncig corrosion.
