GH4169 (718 Alloy) Txias -Trawn Tube Precision thiab Nto Finishing Guide
GH4169 (718 Alloy) Txias -Trawn Tube Precision thiab Nto Finishing Guide
GH4169 (Inconel 718) yog nag lossis daus -nickel hardening-raws li superalloy raj uas yuav tsum tau ua tshwj xeeb txoj kev thaum lub caij txias txias los tswj nws cov kev ua haujlwm siab hardening npaum li cas thiab tswj tau siab precision thiab nto zoo. Txias-raws GH4169 raj yog dav siv nyob rau hauv qhov chaw tseem ceeb xws li aerospace thiab siab - kev siv kub, qhov chaw ruaj khov thiab qhov tseeb ntawm qhov ntev (xws li, txoj kab uas hla / sab hauv txoj kab uas hla ntawm ± 0.015 mm txog ± 0.03 mm) yog qhov tseem ceeb.
Inconel 718 ua haujlwm li cas ntawm qhov kub thiab txias?
Inconel 718 yog nag lossis daus -nickel hardening-raws li alloy tsim los nthuav tawm lub zog siab heev, lub zog tensile, thiab creep rupture lub zog ntawm qhov kub txog li 1300℃F (700℃). Inconel 718 muaj lub hnub nyoog qeeb - cov lus teb nyuaj, yog li ntawd, kev ua kom tawv nqaij tsis tshwm sim thaum cua sov thiab txias, annealing, lossis vuam.
GH4169 Tube raug thiab qhov ntev kam rau ua
Txias -kos GH4169 rajmuab kev tswj qhov ntev zoo heev, tshwj xeeb tshaj yog tsim rau me me - txoj kab uas hla, nyias- cov hlab ntsa.
Dimensional raug:Precision txias txheej txheem tsim cov raj nrogSab nraud txoj kab uas hla (OD)thiab phab ntsa thickness tolerances lub rooj sib tham los yog poob hauv qab noASTM A519 tus qauv.
Outer/Inner Diameter Tolerances:Rau cov ntawv thov precision (piv txwv li, DIN / EN cov qauv), sab nraud txoj kab uas hla rau me me - txoj kab uas hla tuaj yeem khaws cia ntawm± 0.05 hlilos yog tsawg dua.
Phab ntsa Thickness:Phab ntsa thickness kam rau ua yog feem ntau nyob rau hauv10%–12.5%ntawm nominal thickness.
Ncaj nraim: Txias -cov tubes kosFeem ntau pom qhov sib txawv ntawm qhov ncaj ncaj, nrog qhov sib txawv ntawm qhov siab tshaj plaws ntawm 1 hli ib 'meter' ntawm qhov ntev.
Manufacturing theem:Siv ntau-theem txias txheej txheem ua ke nrog nruab nrab annealing (ua hauv argon ntawm850℃-1000 degree), qhov loj me me tuaj yeem ua tiav, xws li 2 hli txheej kab x 0.08 hli phab ntsa tuab.

A. Cov xwm txheej saum npoo av thiab kev kho mob
Tshuaj Annealing thiab Pickling:Tom qab kos duab txias, cov raj feem ntau yog annealed los kho cov ductility thiab pickled kom tshem tawm oxides.
Surface Treatments: Muaj cov kev kho deg muaj xws li ci, polished, thiab hauv av. Kev kho deg tshwj xeeb xws li HL (brushed) lossis4K / 8K (daim iav tiav)muaj rau cov ntawv thov tshwj xeeb.
Polishing:Abrasive polishing compounds yog siv los tshem tawm qhov tsis xws luag thiab txhim kho corrosion kuj.
Laser Polishing:Nruam yoj fiber ntau laser polishing tuaj yeem txo qhov roughness (Ra) ntau dua 80% thiab txhim kho microhardness.
B. Nto Roughness (Ra) Tswj
Txias daim duabtso cai rau deg roughness Ra ntawm 20 mus rau 30 ntiv tes ntawm ob sab nraud thiab sab hauv diameters.
Rau cov ntawv thov tseem ceeb, cov txheej txheem polishing yog ua haujlwm (siv cov ntawv xuab zeb xws li 600 # txog 2500 # hauv ib ntu).
C. Txhim kho lub neej qaug zog dhau ntawm qhov chaw ncaj ncees
Axial Polishing:Axial nto polishing (TCPA) ua tau zoo txhim kho lub neej qaug zog piv rau circumferential polishing (txog 134%).
Sib tsoo:Cubic boron nitride sib tsoo ua rau muaj kev ntxhov siab tseem ceeb (txog -930 MPa), yog li txhim kho kev qaug zog.
