1.What yog cov ntawv thov feem ntau rau K500 Monel?
K500 Monel (tsis yog N05500) yog ib qho nag lossis- tooj liab allloys {} Lub zog allloys}, muaj zog ntxiv, thiab kev ua haujlwm zoo hauv marine thiab kev lag luam zoo. Nws cov ntawv thov feem ntau muaj cov ntsiab lus hauv cov nplais uascorrosion tsis kam thiab nce lub zog (txawm tias muaj qhov kub ntxhov) yog qhov yuav tsum tau ua ib txhij, nrog cov key siv suav nrog:
Marine engineering:
Nws yog dav siv rau cov tub rog tseem ceeb xws li nkoj cov khoom thauj khoom, cov twj tso kua mis, thiab dej hiav txwv {txias sov sov. Cov feem no ua haujlwm hauv cov dej hiav txwv phem- k500} Lub zog citting los ntawm kev hloov pauv ntawm cov neeg kho tshuab ntawm kev sib hloov lossis kev siv tshuab.
Roj & Roj Kev Lag Luam:
Ua haujlwm hauv cov cuab yeej downhole (piv txwv li, tho dauv, cov khoom siv valve), cov khoom siv WAHHEAD, thiab cov khoom xa tuaj ntawm lub nkoj. Nws tiv taus corrosive kua (piv txwv li, branry, hydrogen sulfide, thiab tswj hwm kom haum rau ntug dej siab, ua kom haum rau ntug dej thiab onshore roj cov roj tawm.
Kev Lag Luam:
Siv rau twj tso kua mis impellers, agitators, thiab reactor hauv cov chaw tuav tshuaj corrosive (piv txwv li acids, alkalis, thiab cov kuab tshuaj organic). Nws txoj kev tawm tsam rau ob qho tshuaj tiv thaiv ob qho tib si kev tawm tsam thiab cov kev hnav ua ke kom ua kom muaj kev pabcuam ntev ntev kev pabcuam lub neej nyob rau ib puag ncig.
Aerospace & Tiv Thaiv:
Occassionally siv rau lub tshuab tsim dav hlau (piv txwv li, cov khoom siv roj, cov khoom siv tub rog (piv txwv li cov khoom siv tub rog)
2. Dab tsi yog qhov zoo ntawm K500 Monel?
K500 Monel cov koob meej stems los ntawm nws cov kev sib xyaw ua ke ntawm cov khoom uas ouperform ntau tus txheej txheem hauv corrosive, siab} Kev ntxhov siab ntxhov siab:
Zoo heev corrosion:
Nws tau txais qhov muaj zog corrosion tsis kam ntawm monel 400 (ib npib tsib (-} tooj liab alloy) thiab txhim kho nws ntxiv. Nws tiv taus dej hiav txwv, brines lav, kev lag luam tshuaj, thiab cov pej xeem corrosion (suav nrog hauv nroog) zoo dua li feem ntau stainless hlau thiab tooj liab. Nws kuj tseem ua kom muaj kev tiv thaiv oxidizing me me thiab txo qhov chaw ib puag ncig, nrog tsawg tshaj plaws rau pitting lossis crevice corrosion.
Lub zog siab & hardness (ntawm nag lossis daus daus tawv):
Tsis zoo li tus muag, ductile monel 400, k500 monel ua tiav lub zog siab los ntawm kev ua kev laus cua sov (feem ntau 450-5 kawm tiav / 840-1020℃f). Tom qab cov tawv nqaij tawv, nws lub zog tensile nce mus txog ~ 1100 300 {}}}} {}.
Ua Qauv Zoo & Muaj:
Txawm nyob hauv lub xeev tawv, nws tau tuav tsim nyog tsim nyog ua kom tsim nyog Qhov no tso cai rau nws tsim los ua cov duab ua ke (ntawm kev forging, machining, lossis tiv thaiv kev cuam tshuam me me uas tsis muaj cracking.
Kuj mus rau Biofouling:
Zoo ib yam li tooj liab - nickel alloys, K500 Monel incibits kev loj hlob ntawm kev loj hlob ntawm marine orgets (piv txwv li, algae) ntawm nws nto. Qhov no txo cov nqi txij nkawm rau cov tub rog cov tub rog los ntawm kev tiv thaiv biofouling - indes luag los yog thaiv.
Kev ua tau ruaj khov ntawm kev kub ntxhov:
Nws khaws nws lub zog thiab corrosion tsis kam ntawm qhov kub txog li ~ 31% alloys hauv kev ua kom sov lossis roj av).
3. Dab tsi yog qhov tsis zoo ntawm K500 Monel?
Txawm hais tias nws qhov ua tau zoo, K500 Monel muaj kev txwv uas txwv nws siv hauv qee cov ntawv thov thiab nqi ua haujlwm:
Cov Khoom Siv Ntau Thiab Cov Nqi:
Npib tsib xee (tus thawj tivthaiv, ~ 63% los ntawm qhov hnyav) yog kim, thiab cov ntxiv ntawm txhuas thiab titalis (rau cov nqi nag lossis daus) ntxiv kom cov nqi khoom. Tsis tas li ntawd, nws txoj kev kho cua sov (laus) yuav tsum tau tuav cov khoom kub thiab qhov sib txawv thiab cov nqi sib piv tau monel 400 lossis stainless hlau 316.
Pluag siab -} kub ua tau:
Nws lub zog tsis tshua muaj siab tshaj 315℃/ 600℃F. ntawm theem siab tshaj li 400 degree) pib ua kom muaj zog thiab tensile muaj zog. Qhov kev txwv no txwv nws siv nyob rau hauv high- pa mem tes) qhov twg} palas pa rauv) qhov twg} pa taws ® 718) yog qhov ntau.
Nyuaj machinility:
Nyob rau hauv lub xeev tawv, nws lub siab tawv thiab kev nruj ua tau machining nyuaj. Nws yuav tsum tau cov cuab yeej txiav tshwj xeeb (piv txwv li, carbide lossis cubic boron nitride cov cuab yeej), maj mam txiav nrawm nrawm, thiab txias txias txias siv kom tsis txhob hloov cov cuab yeej thiab overheating. Machining nyob rau hauv lub anealed (mos) lub xeev yooj yim tab sis yuav tsum tau tshaj tawm {4} -}}}} ntxiv cov kauj ruam ntxiv.
Kev ua kom muaj kev ntxhov siab los ntxhov siab corrosion (SCC) hauv ib puag ncig tshwj xeeb:
Thaum corrosion heev - tiv thaiv txhua yam muaj cov kev daws teeb meem uas muaj cov kev daws teeb meem lossis cov khoom siv petrochemical). Qhov no yuav tsum tau soj ntsuam ib puag ncig ib puag ncig thiab, qee kis, kev siv cov kev xaiv lwm yam lossis tiv thaiv kev tiv thaiv.
Ntau dua li lub teeb yuag alloys:
Nrog lub ntom ntom ntawm ~ 8.4 g / cm³er (zoo ib yam li Monel 400), nws yog ntau hnyav dua alloys alloys (~ titanium alloys (~ titanium alloys (~ 4.5 g / cm³). Qhov no ua rau nws tsis tsim nyog rau qhov hnyav-, cov khoom siv dav dav, cov khoom siv portable) uas yog cov nyiam.
