Qhov kev sib xyaw ntawm cov ntsiab lus muab inconel 718 nws cov khoom siv neeg kho kom zoo, oxidation tsis kam, thiab yooj yim ntawm cov fabrication.
4. Dab tsi yog qhov zoo ntawm kev siv Inconel 718 puag ncig cov kab hauv kev lag luam?
Teb:
Siv Inconel 718 puag ncig cov kab muaj ob peb lub ntsiab lus tseem ceeb:
Lub zog siab ntawm cov chaw kub siab: cov kab ke sib tw ua los ntawm Inconel 718 tuaj yeem tswj hwm cov neeg kho mob siab, ua rau lawv muaj kev cuam tshuam rau turbine hniav thiab cov cav sib xyaw.
Kuj yuav ua rau thermal nkees: Incmel 718 tuaj yeem tiv thaiv cov kev hloov pauv tseem ceeb, ua rau nws zoo tshaj plaws rau cov khoom siv thermal.
Corrosion Kuj: Incmel 718 Cov khoom pov thawj pom zoo tsis kam mus rau ntau qhov chaw muaj kev pab ntau, ua kom muaj kev pabcuam ntev txawm tias muaj kev cuam tshuam ntev.
Yooj yim hauv kev ua haujlwm: Inconel 718 puag ncig hloov tau yooj yim machined, drilling, thiab welded, ua rau lawv ntau yam rau ntau cov txheej txheem raug tsim khoom.
Durability: inconel 718 muaj cov hnav zoo heev, txo qhov kev xav tau ntawm cov rep
cov chaw nyob hauv cov khoom tseem ceeb.
5. Yuav ua li cas inconel 718 (GH4169) piv rau lwm qhov siab- kub alloys zoo li inconel 625?
Teb:
Inconel 718(GH4169) thiabInconel 625yog ob qho tib si nickel - Raws li cov ntaub ntawv tab sis yog qhov zoo rau cov ntawv thov sib txawv:
Inconel 718: Paub rau nwsHigh Txhua Yam Zog, cov quav, thiab muaj peev xwm tiv thaiv kom muaj qhov kub siab (txog li 1300℃f lossis 704 degree), inconel 718 yog qhov zoo tagnrho rauib tug tub rogthiabKev thov ib lub tsevQhov twg lub zog muaj zog nyob rau hauv kev ntxhov siab ntau yog qhov tseem ceeb.
