TIAB SA 5662yog cov khoom siv tshwj xeeb rau cov nickel tshwj xeeb -chromium alloy hu ua Inconel 718. Qhov kev qhia tshwj xeeb no yog tswj hwm los ntawm SAE International.ib 718yog nag lossis daus-nickel hardening{1}}chromium alloy uas muaj cov hlau, niobium, molybdenum, txhuas, thiab titanium. Nws yog renowned rau nws zoo heev lub zog thiab corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv high kub.
Kev txiav txim siab AMS 5662: Cov khoom sib xyaw thiab kev kho cua sov
TIAB SA 5662yog cov khoom siv tshwj xeeb tshaj tawm los ntawm SAE International rauTom ntej: Inconel Alloy 718, nag lossis daus -nickel hardenable-chromium- hlau superalloy.
Qhov sib txawv tseem ceeb ntawm AMS 5662 yog nyob rau hauv nws qhov kev kho cua sov zoo:
Qhov xwm txheej:Nws yog muab rau hauv lubkua kub-kho (annealed)xeev.
Metallurgy:Nyob rau hauv no unaged mob, cov khoom tuav qis hardness thiab ntau dua ductility. Qhov no ua rau nws zoo tagnrho rau kev ua haujlwm nyuaj, sib sau, lossis forging cov txheej txheem rau hauv cov duab zaum kawg.
AMS 5663 Kev sib txuas:Tom qab cov khoom yog machined los yog forged rau hauv nws cov duab kawg, nws undergoes nag lossis daus -hardening (hnub nyoog-hardening) thermal voj voog. Cov txheej txheem kev laus no hloov cov khoom siv matrix, txhawb nqa nws cov khoom kom tau raws li qhov siab -lub zogTIAB SA 5663txheem.
Core Material Properties & Engineering Advantages
AMS 5662 Inconel 718 raug xaiv rau kev sib koom ua ke tseem ceeb vim nws qhov tshwj xeeb ua ke ntawm kev ua haujlwm zoo:
- High Yield thiab Tensile Strength:Thaum muaj hnub nyoog- tawv, nws nthuav tawm lub zog zoo heev los ntawm qhov kub thiab txias txog 1300℃F (704℃).
- Superb Corrosion thiab Oxidation Resistance:Cov ntsiab lus siab chromium thiab npib tsib xee tsim muaj kev tiv thaiv muaj zog tiv thaiv kev tawm tsam tshuaj lom neeg, organic acids, thiab siab -kub oxidation lossis scaling.
- Zoo Fatigue thiab Creep Rupture Strength:Resistant micro-fissuring thiab structural deformation nyob rau hauv tas li siab heev- kev co thiab cov neeg kho tshuab kev nyuaj siab nyob rau lub sij hawm ntev.
- Superior Weldability:Tsis zoo li ntau cov laus txhuas-titanium hardened npib tsib xee superalloys, niobium- hloov kho cov qauv ntawm Inconel 718 muab kev tiv thaiv zoo heev rau kev tshaj tawm -weld strain- hnub nyoog tawg.
