N04400 Hoobkas kev nrhiav khoom tsis yog hais txog kev nrhiav qhov qis tshaj plaws - nws yog hais txog kev ruaj ntseg cov ntaub ntawv ua ntej machining txawm pib. Peb tau pom ntau lub twj tso kua mis lub tsev tawg thaum lub sij hawm hydrotesting vim tias daim ntawv pov thawj zeb tsis phim qhov tseeb intergranular corrosion kuj. Ntawm peb qhov chaw Qingdao, txhua qhov N04400 billet-txawm yog rau AMS 5387-raws li cobalt-nickel valve lub rooj lossis T800-alloy winch shafts-ua tiav ob qhov kev pov thawj: spectrometric tsom * thiab * ASTM B164 tensile kuaj ntawm tib lub tshav kub. Qhov ntawd yog li cas peb tiv thaiv "tso ntawv pov thawj tab sis tsis txaus" qhov xwm txheej uas cuam tshuam OEM ncua sij hawm.
Vim li cas "N04400 Hoobkas" txhais tau tias ntau dua li tsuas yog casting lossis dov
Qhov tseeb N04400 kev ua tau zoo hinges ntawm peb qhov tsis sib tham: tswj kev sib koom ua ke, txo qis kev sib cais, thiab tshawb xyuas keeb kwm thermal. Ntau tus neeg muag khoom tau sau cov ntaub ntawv raws li "N04400" tom qab kev kuaj xyuas muaj pes tsawg leeg - tab sis hla kev siv tau ntawm microstructure. Nyob rau hauv kev xyaum, uas ua rau inconsistent machinability: ib batch txiav huv si ntawm 85 m / min; tom ntej no chatters ntawm 45 m / min, yuam cov cuab yeej hloov nruab nrab khiav. Peb lub Hoobkas N04400 koom ua ke lub tshuab nqus tsev induction melting nrog kev taw qhia solidification tswj. Txhua ingot yog mapped rau dendritic spacing thiab sulfur stringer tis-cov ntaub ntawv peb qhia rau cov neeg muas zaub ua ntej txiav. Rau siab li qub xav tau <0.5 μm Ra nto tiav, qhov no tshem tawm kev ua haujlwm tsis tau npaj tseg. Rau piston twj tso kua mis lub tog raj kheej vaj tse ua haujlwm ntawm 4,000 psi, nws tiv thaiv microcrack pib nyob rau hauv cyclic loading.
Qhov twg tus qauv N04400 specs poob luv - thiab peb kaw qhov sib txawv li cas
ASTM B164 txhais tau tias N04400 cov tshuaj txwv txwv - tab sis tsis muaj dab tsi hais txog cov qoob loo ciam teb carbide nag lossis daus kinetics. Qee lub mills xa cov khoom nyob rau hauv spec tab sis tsis ua kom nrawm pitting xeem hauv chloride-nplua nuj hydraulic kua. Peb hais qhov no los ntawm kev tuav tag nrho N04400 Tshuag ntawm 650 ° C rau 2 teev tom qab annealing, ces cua txias. Qhov no stabilizes Ni-Cu matrix tiv thaiv xaiv leaching thaum khaws cia ductility. Cov neeg siv khoom qhia 3.2 × ntev kev pab cuam lub neej nyob rau hauv offshore twj tso kua mis sib dhos siv qhov kev kho no. Qhov tseem ceeb, peb tsis kho txhua pawg tib yam: cov ntsiab lus sulfur> 0.005% ua rau ncua sij hawm tuav; titanium residuals> 0.02% hloov cov cua txias. Kev hloov pauv hauv ntiaj teb tiag tiag xav tau cov lus teb ntawm lub sijhawm metallurgical-tsis yog cov txheej txheem zoo li qub.
Los ntawm raw bar mus rau lub hom phiaj tseem ceeb ib feem: qhov ntsug kom zoo dua
Feem ntau N04400 cov chaw muag khoom nres ntawm cov khoom siv. Peb pib muaj-thiab muaj txhua kauj ruam tom qab. Thaum ib tug European OEM xav tau 120 kev cai-zoo li tus cobalt alloy nozzles rau high-temperature slurry txhaj, lawv xa peb daim duab nrog ± 0.01 hli GD&T callouts thiab 10-lub lim piam hnub kawg. Nov yog qhov tshwm sim: peb cov kws tshawb fawb metallurgists tau txheeb xyuas qhov N04400 billet qhov profile kub ua haujlwm ua ntej; peb pab neeg CNC simulated nti load faib thoob plaws hauv txoj kev contours; peb cov pab pawg ua tiav validated electropolish tsis tiv thaiv ASTM A967 passivation yuav tsum. Tsis muaj handoffs. Tsis muaj kev ncua sij hawm thib peb. Txhua qhov chaw soj ntsuam - los ntawm cov khoom xa tuaj CMM scans mus rau cov ntaub ntawv xau-kuaj zaum kawg-nyob hauv ib lub xov tooj digital. Tias yog vim li cas 73% ntawm peb cov lus txib N04400 rov ua haujlwm rau tib lub luag haujlwm.
Xaiv koj lub koom haum N04400: peb cov lus nug uas nthuav tawm lub peev xwm
- Koj puas tuaj yeem qhia kuv txog peb qhov kev ntsuas kub kawg 'cov ntaub ntawv ntsuas tag nrho - suav nrog kev sib xyaw ua ke (ASTM G28 Txoj Kev A) thiab kev ntsuas qeeb qeeb hauv 3.5% NaCl? Yog tias lawv tsis kam, lawv QA nres ntawm chemistry.
- Koj puas tshuab N04400 hauv tsev-lossis outsource tom qab xa khoom? Off-site machining lov thermal keeb kwm txuas ntxiv thiab muaj kev pheej hmoo ntawm kev sib kis.
- Dab tsi yog koj qhov kev ua haujlwm ntev tshaj plaws N04400 ntau lawm - thiab hom kev ua haujlwm twg koj tau tshem tawm los ntawm cov txheej txheem rov ua dua? Cov lus teb qhia seb lawv kawm los ntawm cov ntaub ntawv teb lossis tsuas yog daim ntawv pov thawj nkoj.
Peb tau khiav tib lub N04400 twj tso kua mis qhov kev pab cuam rau yim xyoo. Thaum ntxov batch pom micro-pitting ntawm bearing interfaces. Hauv paus ua rau? Tsawg manganese oxide suav nrog ua raws li kev ntxhov siab concentrators. Kev daws: ntxiv calcium kev kho rau yaj thiab qhia ultrasonic immersion tu ua ntej machining. Qhov ntawd tsis yog kev tsim khoom nkaus xwb - uas yog kev tswj hwm kev lag luam metallurgical. Thaum koj xav tau kev txhim khu kev qha Nickel Alloy 400 ntau lawm, pib qhov twg cov khoom siv zaj dab neeg pib - tsis yog qhov twg daim ntawv them nqi ua.
