3. Inconel 718, 625, thiab 600 txawv li cas ntawm lawv cov khoom siv rau kev tsim kho?
Teb:
Txhua yam ntawm cov alloys no muaj qhov sib txawv ntawm qhov sib txawv thiab haum rau ntau yam kev tsim kho:
Inconel 718: Paub txog lub zog txhua yam ntawm qhov kub siab (txog 1300℃F / 704 degree). Qhov zoo tshaj plaws rau siab - qhov kub ntawm cov qauv uas yuav tsum tau ua kom muaj kev kub ntxhov siab heev thiab thermal cycling.
Inconel 625: Superior corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv marine thiab tshuaj ib puag ncig, muaj zog tensile siab. Qhov zoo tshaj plaws rau cov khoom uas raug sulfuric acid, dej hiav txwv, lossis cov tshuaj lom neeg hnyav.
Inconel 600: Zoo heev oxidation thiab corrosion kuj ntawm qhov kub siab (txog 2000℃F / 1093 degree), ua rau nws zoo tagnrho rau siab -cov khoom cua sov xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
4. Dab tsi yog cov cuab yeej cuab tam ntawm Inconel 718, 625, thiab 600 daim hlau uas muaj txiaj ntsig zoo rau kev tsim kho?
Teb:
Tensile Strength: Tag nrho peb cov alloys muaj lub zog tensile siab, ua kom muaj kev ncaj ncees nyob rau hauv kev xav tau kev tsim kho ib puag ncig uas cov neeg siv khoom muaj zog ua si.
Fatigue Resistance: Inconel 718 thiab 625 muaj kev qaug zog zoo heev, tshwj xeeb tshaj yog qhov tseem ceeb rau qhov chaw raug thermal cycling thiab rov ua haujlwm hnyav.
Oxidation thiab Corrosion Resistance: Inconel 600 thiab 625 excel nyob rau hauv oxidation kuj, tiv thaiv cov khoom ntawm degradation nyob rau hauv siab - kub thiab corrosive ib puag ncig.
Creep Resistance: Inconel 718 yog tsim tshwj xeeb rau kev nkag siab zoo nyob rau hauv qhov kub thiab txias, kom ntseeg tau ntev -lub sij hawm ua haujlwm nyob rau hauv huab cua.
5. Cov teeb meem dab tsi cuam tshuam nrog kev siv Inconel 718, 625, thiab 600 daim phiaj hauv kev tsim kho?
Teb:
Machining nyuaj: Inconel alloys yog tawv thiab tiv taus hnav, ua rau lawv nyuaj rau tshuab. Cov cuab yeej tshwj xeeb thiab kev txiav qeeb qeeb yuav tsum tau zam kom tsis txhob hnav ntau dhau.
Vuam Teebmeem: Cov alloys no yuav tsum tau preheat thiab tom qab-welding kev kho cua sov kom tsis txhob muaj teeb meem xws li tawg lossis poob lub zog tom qab vuam.
Tus nqi: Inconel alloys kim dua lwm cov ntaub ntawv xws li stainless hlau lossis carbon hlau, uas tuaj yeem cuam tshuam rau tag nrho cov phiaj xwm phiaj xwm, tshwj xeeb tshaj yog nyob rau hauv loj - kev tsim kho.
Ua Haujlwm Hardening: Inconel alloys tuaj yeem ua haujlwm tau- tawv sai sai thaum lub sijhawm ua haujlwm txias, yog li yuav tsum tau ua tib zoo saib xyuas kom tsis txhob tawg lossis hnyav dhau thaum tsim khoom.
