1. Inconel 718 (W. Nr. 2.4668) yog dab tsi thiab nws daim ntawv thov tseem ceeb?
Teb:
Inconel 718 (W. Nr. 2.4668) yog lub siab -kev ua tau zoo, npib tsib xee-raws li superalloy paub txog nws cov khoom siv kho tshuab zoo heev ntawm qhov kub thiab txias thiab nws tiv thaiv oxidation thiab corrosion. Nws yog feem ntau siv hauv kev lag luam xws li aerospace, tshuaj ua haujlwm, thiab tsim hluav taws xob, tshwj xeeb tshaj yog rau cov khoom siv uas ua haujlwm nyob rau hauv qhov chaw huab cua xws li turbine blades, foob pob hluav taws cav, thiab siab - cov tshuab siab.
2. Dab tsi yog qhov txawv ntawm seamless thiab welded Inconel 718 kav?
Teb:
Seamless Inconel 718 Yeeb Nkab: Cov yeeb nkab tsis muaj seamless yog tsim tsis muaj cov welded seams, muab cov qauv zoo ib yam thiab muaj zog dua, tshwj xeeb tshaj yog haum rau siab - siab thiab siab - kev siv kub.
Welded Inconel 718 Yeeb Nkab: Welded kav yog tsim los ntawm vuam ib lub tiaj tiaj ntawm cov hlau rau hauv cov yeeb nkab. Txawm hais tias feem ntau tus nqi ntau dua - siv tau, cov kav dej welded tej zaum yuav muaj qhov tsis sib xws lossis tsis muaj zog ntawm cov ntsiab lus vuam tab sis tseem siv dav hauv cov ntawv thov tseem ceeb uas tsis muaj kev txhawj xeeb siab tshaj plaws.
3. Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm Inconel 718 kav / raj yog dab tsi?
Teb:
Inconel 718 kav dej feem ntau tuaj yeem ua haujlwm ntawm qhov kub txog li 700℃(1,300℃F) tsis tu ncua, nrog luv luv -lub sij hawm raug rau qhov kub siab dua (txog li 800℃). Cov hlau nplaum khaws cov khoom zoo heev ntawm qhov kub siab, uas yog vim li cas nws feem ntau siv rau hauv lub cav turbine thiab reactors qhov siab - qhov kub thiab txias yog qhov tseem ceeb.
4. Inconel 718 ua haujlwm li cas ntawm kev tiv thaiv corrosion?
Teb:
Inconel 718 muaj kev tiv thaiv zoo heev rau ntau hom kev xeb, suav nrog pitting, crevice corrosion, thiab oxidation, tshwj xeeb tshaj yog nyob rau hauv siab - qhov kub thiab txias. Nws cov ntsiab lus siab nickel thiab qhov sib ntxiv ntawm lwm cov ntsiab lus xws li chromium muab kev tiv thaiv zoo heev rau corrosion, ua rau nws tsim nyog rau kev siv hauv ib puag ncig hnyav xws li kev ua tshuaj lom neeg thiab kev siv dej hiav txwv.
5. Dab tsi yog qhov dav thiab cov qauv rau Inconel 718 cov kav dej / raj?
Teb:
Inconel 718 cov kav dej muaj nyob rau hauv ntau qhov ntau thiab tsawg, xws li cov raj me me (li nyias li 6 hli nyob rau hauv txoj kab uas hla sab nraud) mus rau loj - cov kav dej (txog li ob peb nti hauv txoj kab uas hla). Cov kav dej feem ntau muaj nyob rau hauv cov txheej txheem raws li Schedule 40 thiab Schedule 80, thiab lawv ua raws li cov qauv kev lag luam xws li ASTM B163, ASTM B705, lossis ASTM B622. Lawv tuaj yeem tsim tau raws li cov neeg siv khoom tshwj xeeb hais txog qhov ntev, tiav, thiab phab ntsa thickness.
