Dab tsi yog qib inmpeet 718?
Inconel 718 yog Gmma Prime Harden Alloy nrog cov kws kho zoo ntawm cov khoom siv siab thiab qis. Haum rau qhov kub txog li ntawm txog 1300 F. yooj yim machined thiab hnub nyoog tawv.
Lub zog zoo los ntawm -423 degree f rau 1300 degree f ({-253 degree rau 705 degree). Lub hnub nyoog nyuaj, weldable nyob rau hauv cov kev mob siab, zoo oxidation tiv taus 1800 degree f (980 degree). Feem ntau muag hauv kev daws analials mob, tab sis tuaj yeem xaj tau ua hnub nyoog, txias ua haujlwm, lossis ua haujlwm txias thiab laus.
Cov Ntawv Thov
Inconel 718 siv zoo li yuav nyob hauv thaj chaw ntawm cov av ntawm cov roj thiab cryogenic tso tsheb hlau luam. Dav hlau tshuab, tshuab lub cev thiab cov chaw, pob zeb tshuab thiab tshuab revust, nuclear roj zaub gaskets, kub extrusion cov cuab yeej. Lwm cov kev siv yog qhov siab lub zog bolts thiab downhole shafting.
