Thaum xaiv nickel-raws li superalloys, machinability yog qhov tseem ceeb, cuam tshuam ncaj qha rau cov nqi tsim khoom, lub sijhawm xa khoom, lub neej ntawm lub cuab yeej, thiab kev ua haujlwm tag nrho. Ntawm cov qib siv feem ntau, Inconel 625 thiab Inconel 718 feem ntau tau muab piv rau vim lawv cov qib siab zoo heev - qhov kub thiab txias tsis kam ua haujlwm -tab sis lawv muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm.
Inconel 625 (UNS N06625) yog dab tsi?
Inconel 625 yog ib qho khoom siv -kev daws teeb meem muaj zog nickel-chromium- molybdenum alloy nrog ntxiv niobium.
Nws tsis cia siab rau nag lossis daus hardening, yog li nws muaj kev ua haujlwm zoo dua piv rau ntau lub hnub nyoog -hardened superalloys. Nws yog tsim rau cov roj thiab cov kav dej, cov khoom siv tshuaj, cov khoom siv hauv hiav txwv, thiab cov khoom siv hluav taws xob.
Inconel 718 (UNS N07718) yog dab tsi?
Inconel 718 yog nag lossis daus-nickel hardened-raws li superalloy, feem ntau ntxiv dag zog los ntawm 'thiab' theem tsim tom qab kev laus kho. Cov qauv no ua rau nws muaj zog heev, tab sis kuj ua rau nws nyuaj rau tshuab. Nws yog tsim rau cov khoom siv hauv aerospace, roj turbines, siab - lub zog fasteners, thiab cov khoom siv nuclear.

inconel 625 vs 718: kev ua haujlwm
Piv nrog rau Inconel 718, Inconel 625 feem ntau yog yooj yim dua rau tshuab vim 718 nthuav tawm ntau dua ntawm kev ua haujlwm hardening, ua rau nws nyuaj rau txiav, tshwj xeeb tshaj yog tom qab hardening kev kho cua sov (xws li, nyob rau hauv cov xwm txheej raws li AMS 5663). Thaum 625 tseem tawv heev, nws tsis tawv sai li 718, ua rau lub neej ruaj khov dua. Nyob rau hauv sib piv, 718 yuav tsum tau tshwj xeeb machining cov tswv yim, txo txiav ceev, thiab yog feem ntau machined nyob rau hauv lub softer tov - kho mob (raws li AMS 5662) los tiv nrog nws tsis tshua muaj siab hardness thiab siab zog ntawm siab kub.

| Alloy | Tus txheeb ze Machinability |
|---|---|
| Ib 625 | ~ 30 |
| Inconel 718 (Kev daws teeb meem) | ~ 25 |
| Inconel 718 (hnub nyoog) | ~ 20 |
Puas yog Inconel 625 yooj yim rau tshuab dua Inconel 718?
Yog lawm. Inconel 625 feem ntau muaj kev ua haujlwm zoo dua vim tias nws muaj zog- kev daws teeb meem ntxiv zog thiab tsis xav tau kev kho kev laus, ua rau qis zog thiab txo cov cuab yeej hnav.
Vim li cas Inconel 718 thiaj li nyuaj rau tshuab?
Inconel 718 ua haujlwm- hardens sai, muaj zog txiav siab heev, thiab tuav lub zog ntawm qhov kub thiab txias, ua rau cov cuab yeej hnav hnyav thiab tswj cov nti tsis zoo.
Inconel 718 puas tuaj yeem ua haujlwm ua ntej kev kho cua sov?
Yog lawm. Machining Inconel 718 hauv kev daws teeb meem -annealed mob tau pom zoo kom txo cov cuab yeej hnav thiab txhim kho kev tswj qhov ntev.
Txawm hais tias ob qho tib si Inconel 625 thiab Inconel 718 yog siab -kev ua tau zoo nickel alloys, machinability yog qhov txiav txim siab. Los ntawm kev tsim khoom thiab tus nqi- qhov pom kev ua tau zoo, Inconel 625 muaj qhov zoo sib xws, thaum Inconel 718 ua tau zoo hauv cov ntawv thov uas xav tau lub zog siab thiab hnyav.
