Inconel 718 vs Inconel 625

Qee cov ntawv thov kev lag luam siab tshaj plaws niaj hnub no-tshwj xeeb tshaj yog nyob rau hauv aerospace, automotive, thiab roj thiab roj kev lag luam- cia siab rau cov ntaub ntawv alloy nrog lub zog tshwj xeeb thiab kev ua haujlwm zoo. Ntawm cov ntaub ntawv no yog ob lub superalloys hu ua Inconel 718 thiab Inconel 625. Cov Inconel alloys ua ke yog siv nyob rau hauv ntau yam khoom uas yuav tsum tau muaj zog, kub tsis kam, thiab muaj zog corrosion kuj. Nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm Inconel 718 vs. Inconel 625 hauv kev txiav txim siab uas superalloy tuaj yeem ua tau raws li qhov kawg ntawm kev siv cov txheej txheem tsim khoom.

Inconel 718 thiab Inconel 625 qhia ntau yam khoom ntawm Inconel alloy tsev neeg thiab ntau yam khoom ntawm cov nickel alloy thiab stainless hlau tsev neeg. Txawm li cas los xij, lawv kuj muaj qhov txawv txav uas ua rau muaj kev siv tshwj xeeb.

Inconel 625 yog tsim los ntawm nickel thiab chromium. Nws kuj suav nrog molybdenum thiab niobium, uas muab rau nws lub zog tensile siab thiab corrosion kuj, nrog rau kev tiv thaiv rau crevice corrosion. Columbium thiab molybdenum account rau nws lub zog siab nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias los yog kub heev. Inconel 625 tuaj yeem tswj hwm nws lub zog hauv ib puag ncig txog 2,000℃F, thiab raws li nws cov ntawv tshaj tawm, nws muab kev tiv thaiv oxidation zoo thiab ua haujlwm rau carburization.

Inconel 718 feem ntau muaj cov tshuaj zoo sib xws rau Inconel 625, nrog cov kev hloov me me. Inconel 718 yog qhov zoo tshaj plaws rau nws lub peev xwm los nag lossis daus nyuaj yam tsis tau ua tiav rau kev tshaj tawm -weld cracking, kuj raws li cov ntawv xov xwm txuas rau saum toj no. Nws kuj tseem tuaj yeem tiv taus qhov tawg ntawm qhov kub txog li 1,300℃F. Vim tias qhov muaj peev xwm no, Inconel 718 tuaj yeem tuav lub zog tensile siab thaum tseem muaj cov yam ntxwv zoo li cov qauv siab.

High weldability ua rau Inconel 718 zoo ib yam li qee txoj hauv kev rau cov qib stainless hlau dav dav. Inconel 625 nyob rau hauv annealed mob, ntawm qhov tod tes, tuaj yeem ua kom muaj zog dua thiab, raws li tau hais, tshwj xeeb tshaj yog haum rau kev tiv thaiv corrosion, suav nrog qhov tshwm sim los ntawm dej hiav txwv ib puag ncig.

Lub siab concentration ntawm nickel nyob rau hauv ob hom ntawm Inconel alloy ua rau feem ntau siab formability. Ob leeg Inconel 718 thiab 625 tuaj yeem raug stamped thiab txias tsim. Txawm hais tias ob qho tib si muaj lub zog tensile tshwj xeeb, Inconel 718 qhov tsis kam tshaj tawm -weld, lossis strain- hnub nyoog, tawg thaum kho cua sov ua rau nws tshwj xeeb tshaj yog haum rau formability thaum tuav lub zog siab hauv ib qho kev mob annealed.

Vim tias qhov zoo ntawm Inconel alloy, cov ntaub ntawv no tuaj yeem dov los ntawm cov hlau zeb los tsim ntau yam hlau profiles rau kev lag luam xws li aerospace thiab roj thiab roj. Lawv kuj tuaj yeem siv los tsim cov honeycombs, foob rings, bellows, thiab springs. Lawv kuj ua hauj lwm ua tau zoo fastener alloys rau huab cua, nrog rau cov uas yuav muaj corrosion.

Ob leeg Inconel 718 thiab 625 tuaj yeem siv rau ntau hom kev tsim khoom. Cov ntaub ntawv khoom muaj xws li sawb, ribbon, thiab zoo li tus xaim, nrog rau puag ncig, tiaj tus, thiab square xaim. Qhov tseem ceeb, tsis yog ob hom alloy no feem ntau sib sib zog nqus nqus.

Ob lub superalloys tuaj yeem siv rau ntau yam khoom siv stamped- xws li lub diaphragm rau lub ntsuas ntsuas ntsuas. Lawv pab tau tshwj xeeb tshaj yog thaum tiv taus qhov kub thiab txias thiab siab - xav tau kev kub ntxhov. Inconel 625 tshwj xeeb yog siv rau cov hlau hloov pauv tau yooj yim, cov khoom siv hluav taws xob sib hloov, cov kab taub hau, thiab cov khoom siv hauv hiav txwv vim nws lub zog loj heev hauv cov cheeb tsam ntawm qhov kub thiab txias, nrog rau nws cov oxidation tsis kam.

Raws li twb tau hais lawm, Inconel 718 tau pib nws lub neej nyob rau hauv kev lag luam aerospace thiab tsuas yog muaj ntau dua nyob rau hauv qhov chaw ntawd. Raws li ib txoj kev tshawb fawb, cov hlau ua rau ntau tshaj 30 feem pua ​​​​ntawm cov tshuab dav hlau niaj hnub ua tiav cov khoom loj. Lub dav hlau cav yog ib qho cuab yeej siv rau qhov kub thiab txias alloy uas tuaj yeem tuav tau nyob rau hauv lub siab, siab corrosive ib puag ncig ntawm burning dav hlau roj thiab txawv tshaj plaw propulsion.

Ib yam li ntawd, lub tsheb cav tsim siab - qhov chaw muaj kev ntxhov siab rau cov khoom siv alloys. Ntau yam ntawm lub tsheb cav tau txais txiaj ntsig los ntawm kev siv lub superalloy nrog siab formability muab los ntawm cov ntsiab lus npib tsib xee. Ib qho Inconel alloy tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb ntawm cov ntawv thov hauv lub cav tsheb thaum tseem tswj hwm qhov kev tiv thaiv corrosion siab uas xav tau los xyuas kom ntev - lub sij hawm cia siab.

Vim nws cov corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv hiav txwv ntsev ib puag ncig, Inconel 625 muaj ntau marine kev lag luam siv thiab. Qhov no suav nrog cov kev xav tau ntawm kev lag luam roj thiab roj, xws li downhole drilling daim ntawv thov xws li khi rov qab ntawm cov kab hauv qab. Inconel 625 kuj tseem siv rau hauv dej hiav txwv ib puag ncig rau kev sib txuas lus kab, kiv cua, thiab hlua hlua.

Rau engineers thiab manufacturers, to taub qhov sib txawv ntawm ntau yam hlau khoom loj heev, xws li stainless hlau, npib tsib xee alloys, thiab superalloys zoo li Inconel 718 thiab 625, yog ib qho tseem ceeb heev. Ib yam tseem ceeb yog kev nkag siab tias cov alloys no teb li cas rau ntau yam kev ua, xws li stamping, sib sib zog nqus nqus, yob txoj kev, thiab micro- laser vuam. Txawm tias cov kws tshaj lij cov neeg yuav khoom thiab cov kws paub txog kev siv tshuab tuaj yeem tau txais txiaj ntsig los ntawm cov kws tshaj lij ntawm cov kws tshaj lij metallurgical uas muaj nyob rau hauv - kev paub tob ntawm cov khoom siv hlau thiab kev siv. Pab neeg GNEE muaj kev txawj ntse heev los pab cov neeg siv khoom los tsim cov hlau zoo tshaj plaws rau lawv qhov kawg - siv cov kev cai.

Peb cov khoom siv nickel-raws li cov khoom siv hlau yog tsim los ntawm cov khoom siv niaj hnub precision manufacturing puag. Lub Hoobkas tau nruab nrog lub tshuab nqus tsev vacuum induction melting (VIM), electroslag remelting (ESR), thiab multi-directional forging hydraulic units, kom ntseeg tau tias txhua kauj ruam los ntawm melting mus ua tau raws li aerospace- cov qauv qib. Los ntawm kev tswj cov txheej txheem digital, peb ua tiav kev tswj xyuas meej ntawm cov khoom siv purity, grain loj, thiab txhua yam khoom. Txhua batch ntawm cov khoom yog nrog los ntawm traceable melting cov ntaub ntawv thiab thib peb - cov ntaub ntawv pov thawj (xws li DNV-GL, ABS, aerospace qauv, thiab lwm yam), kom ntseeg tau qhov tseeb thiab kev ntseeg siab ntawm cov ntaub ntawv kev ua tau zoo.

Peb txais yuav cov qauv kev lag luam siab tshaj plaws rau kev ntim khoom tiv thaiv: tag nrho cov pas nrig / daim hlau raug kho nrog kev tiv thaiv- xeb tiv thaiv thiab ntxiv dag zog rau cov yeeb yaj kiab tsis muaj dej thiab cov khoom ntoo; precision Cheebtsam yog ntim nrog kev cai ua npuas ncauj dividers thiab lub tshuab nqus tsev sealing. Los ntawm peb cov txheej txheem kev sib koom ua ke ntawm kev tsim khoom, peb cog lus tias cov khoom lag luam tshwj xeeb yuav raug npaj thiab xa tuaj tsis pub dhau 7-15 hnub ua haujlwm tom qab kev txiav txim pom zoo thiab cov ntsiab lus kev ua tiav.
