Cov lus qhia dav dav rau nickel-based alloys: Monel 401 (UNS N04401)
Monel 401 (tseem hu ua "Alloy 401"), tsim los ntawm UNS N04401, yog tooj liab-nickel alloy tsim rau tshwj xeeb siv hluav taws xob thiab hluav taws xob. Nws muaj qhov kub tsis tshua muaj coefficient ntawm kev ua haujlwm thiab nruab nrab-nruab nrab resistivity. Alloy 401 tuaj yeem yooj yim welded los ntawm roj tungsten arc vuam (GTAW) los yog tsis kam vuam. Monel 401 feem ntau yog muab rau hauv daim ntawv hlau thiab feem ntau yog siv rau cov hlau-qhov txhab precision resistors thiab bimetal hu. Monel 401 yog ib qho khoom siv tooj liab-nickel alloy uas tsis tshua muaj kev tiv thaiv thiab tsis kam mus rau ntau yam kev mob corrosive. Zoo li kev lag luam ntshiab npib tsib xee, Monel 401 tsis tshua muaj zog nyob rau hauv cov mob annealed thiab tsuas tuaj yeem ua haujlwm txias rau qhov siab tshaj plaws ntawm 120 KSI.
High-temperature alloy Monel 401 muaj cov ntsiab lus tooj liab ntau dua li cov hlau kub kub Monel 400.
Machinability ntawm Monel 401
Cov txheej txheem machining ib txwm siv rau ferrous alloys tuaj yeem siv rau cov hlau no.
Vuam Monel 401
Alloy 401 tau yooj yim txiav welded rau hauv cov ntawv nyias. Gas tungsten arc welding yog ib qho kev siv vuam thiab txheej txheem vuam. Kev tiv thaiv vuam yog ib txoj kev txaus siab rau cov hlau no. Cov txheej txheem welding feem ntau haum rau cov hlau no. Kev sib xyaw ua ke ntawm cov hlau nplaum yuav tsum tau siv. Yog tias tsis muaj qhov sib txuam alloy, qhov ze tshaj plaws alloy nplua nuj nyob hauv cov tshuaj lom neeg muaj pes tsawg leeg (Ni, Co, Cr, Mo) yuav tsum tau siv. Txhua weld hlaws yuav tsum me ntsis convex. Tsis tas yuav siv preheating. Qhov chaw yuav tsum tau welded yuav tsum huv si thiab tsis muaj roj, pleev xim los yog crayon cim. Qhov chaw tu yuav tsum ncua tsawg kawg 2 ntiv tes dhau ntawm ob sab ntawm qhov sib koom ua ke.
Gas tungsten arc vuam: Nws raug nquahu kom siv DC zoo electrode (tsis zoo electrode). Khaws lub arc ntev kom luv li sai tau thiab ceev faj kom qhov kub kawg ntawm cov hlau muab tub lim nyob rau hauv qhov chaw tiv thaiv txhua lub sijhawm. Shielded Hlau Arc Vuam: Electrodes yuav tsum muab cia qhuav thiab yog damp, lub electrode yuav tsum tau ci ntawm 600 F rau ib teev kom qhuav. Cov chaw tam sim no muaj li ntawm 0.062 amps rau 50- cov ntaub ntawv tuab tuab rau 2 amps rau 190 / 1- ntiv tes thiab cov ntaub ntawv tuab. Nws yog qhov zoo tshaj rau me ntsis braid lub electrode vim qhov no alloy weld hlau tsis kis tau yooj yim. Siv txhuam txhuam (tes los yog hluav taws xob) los ntxuav cov slag. Nws yog ib qho tseem ceeb kom tshem tawm tag nrho cov slag ua ntej ua tiav thiab tom qab qhov kawg vuam.
Gas Hlau Arc Vuam: Rov qab polarity DC yuav tsum tau siv, nrog cov txiaj ntsig zoo tshaj plaws thaum lub vuam phom yog 90 degrees rau qhov sib koom ua ke. Rau luv luv-circuit hloov GMAW, raug voltage yog 19-25, tam sim no yog 100-175 amps, thiab xaim pub ceev yog 225-400 ntiv tes ib feeb. Rau cov tshuaj tsuag hloov GMAW, qhov voltage yog 26 mus rau 33, tam sim no yog 200-350 amps, thiab cov xaim pub ceev yog 200-500 ntiv tes ib feeb, nyob ntawm qhov muab tub lim txoj kab uas hla.
Submerged arc welding: Tib qhov sib txuam cov hlau ua rau GMAW yuav tsum tau siv. DC tam sim no nrog rov qab los yog pem hauv ntej polarity tuaj yeem siv tau. Qhov projection welds yog nyiam.
Thermal processing ntawm Monel 401
Thermal processing yuav ua tau yog tias tsim nyog.
Kev ua haujlwm txias ntawm Monel 401
Txias txoj kev tuaj yeem ua tiav siv cov pwm pwm thiab cov khoom siv pwm kom ua tiav qhov zoo dua. Kev sib sau txias tuaj yeem ua tiav siv cov cuab yeej txheem, tab sis nws tsis pom zoo kom siv cov cuab yeej carbon zoo tib yam rau kev sib sau vim tias lawv nyiam hnav. Cov khoom siv pwm mos (bronze, zinc alloys, thiab lwm yam) txo qis hnav thiab ua kom tiav, tab sis pwm lub neej luv luv. Rau kev tsim khoom mus ntev, cov cuab yeej hlau hlau (D-2, D-3) thiab cov hlau kub ceev (T-1, M-2, M-10 ) muab cov txiaj ntsig zoo, tshwj xeeb tshaj yog tawv chromium plating kom txo tau hnav. Cov cuab yeej yuav tsum pub dawb clearance thiab radii. Cov roj nplua nyeem hnyav yuav tsum tau siv los txo qis hnav hauv txhua qhov haujlwm molding. Ib-degree khoov nyob rau hauv daim ntawv los yog phaj feem ntau txwv rau ib tug khoov vojvoog ntawm 8 T rau cov ntaub ntawv thicker dua 180/1 nti thiab mus rau 8 T rau cov ntaub ntawv thicker dua 2/1 nti.
Hardened Monel 401
Hardened tsuas yog ua haujlwm txias.
Monel 401 Annealed
Monel 401 alloy yuav tsum tau muab tso rau ntawm 760 degree (1400 degree f) rau ib teev kom rov qab los ntawm kev ua haujlwm txias.
Kev kho cua sov Monel 401
Tsis muaj kev kho cua sov yog tso cai tshwj tsis yog rau annealing tom qab ua haujlwm txias.
