1. Dab tsi yog cov ntawv thov tseem ceeb ntawm Inconel 625 (UNS N06625) hauv kev lag luam aerospace thiab siab -kev lag luam kub?
Teb:
Inconel 625 yog npib tsib xee-chromium- molybdenum alloy paub txog nws lub zog siab, zoo corrosion kuj, thiab oxidation kuj ntawm qhov kub siab. Nws cov ntawv thov aerospace suav nrog:
Jet engine Cheebtsam (turbine blades, exhaust systems)
Gas turbine qhov chaw
Aerospace fasteners thiab structural Cheebtsam
High -cov khoom siv tshuaj ua haujlwm kub
Nws yog qhov zoo tshaj plaws uas yuav tsum tau muaj ob qho tib si thermal stability thiab kev tiv thaiv rau qhov chaw nruj heev.
2. Dab tsi yog cov khoom tseem ceeb ntawm Inconel 625 tuav?
Teb:
Chav ntsuas kub: Tensile zog ~ 827-1,000 MPa, yield zog ~ 414-552 MPa, elongation ~ 30-40%.
Kev kub siab (~ 870℃/ 1,600℃F): tuav lub zog zoo, nkag siab, thiab thermal stability.
Hardness: ~ 200-250 HB (Brinell) nyob rau hauv cov mob annealed.
Kev sib xyaw ua ke ntawm lub zog siab thiab ductility ua rau nws tsim nyog rau kev thov aerospace thiab kev lag luam.
3. Inconel 625 tiv thaiv corrosion thiab oxidation li cas?
Teb:
Cov ntsiab lus siab nickel muab kev tiv thaiv rau oxidizing ib puag ncig.
Chromium thiab molybdenum txhim khu kev tiv thaiv rau pitting, crevice, thiab kev nyuaj siab corrosion cracking.
Ua kom ruaj khov, tiv thaiv oxide txheej nyob rau hauv siab -kub thiab corrosive cua, tiv thaiv degradation nto.
Muaj peev xwm tiv taus ntau yam acids thiab dej hiav txwv, ua rau nws haum rau marine thiab tshuaj ib puag ncig ib yam nkaus.
4. Inconel 625 cov qauv thiab specifications li cas?
Teb:
ASTM B446 - Txuj Specification rau Nickel -Chromium-Molybdenum Alloy Bars
UNS N06625 - Kev Sau Npe Sau Npe Ua Haujlwm
AMS 5662 / AMS 5383 - Aerospace specifications rau tshuaj muaj pes tsawg leeg thiab txhua yam khoom
Kev ua raws cai ua kom cov khoom zoo sib xws thiab kev ua tau zoo rau cov khoom siv aerospace thiab cov khoom lag luam tseem ceeb.
5. Dab tsi yog qhov kev txiav txim siab rau Inconel 625 tuav?
Teb:
Machining: tuaj yeem nyuaj vim ua haujlwm nyuaj; siv cov cuab yeej ntse, tus nqi pub tsawg, thiab cov dej txias tsim nyog.
Vuam: Zoo heev weldability nrog feem ntau npib tsib xee-raws li vuam hlau; preheating tsis feem ntau yuav tsum tau.
Kev kho cua sov: Annealing (1,090-1,120 degree) rov qab ductility tom qab fabrication; tsis muaj kev laus yuav tsum tau kho vim nws tsis yog nag lossis daus hardened.
Kev tsim: tuaj yeem ua haujlwm kub lossis txias, tab sis kev ua haujlwm kub yog nyiam rau cov duab nyuaj.
Ua raws li cov lus qhia no ua kom cov khoom khaws cia nws cov kev tiv thaiv corrosion, cov khoom siv kho tshuab, thiab qhov tseeb qhov tseeb.
