Hais txog cov khoom siv kho tshuab, NCF800 nthuav tawm lub zog tensile zoo thiab ductility. Nws tuaj yeem tiv taus cov khoom hnyav thiab kev ntxhov siab txhua yam yam tsis muaj succumbing rau brittle tsis ua hauj lwm. Qhov kev sib xyaw ua ke ntawm lub zog thiab yoog raws tso cai rau kev tsim cov txheej txheem nyuaj thiab ruaj khov. Tsis tas li ntawd, cov hlau nplaum muaj qhov ua tau zoo heev, uas txhais tau tias nws tuaj yeem tswj tau nws cov duab thiab qhov ntev nyob rau hauv lub sij hawm ntev raug rau qhov kub thiab txias tsis tu ncua. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas qhov kev ruaj ntseg yog qhov tseem ceeb, xws li hauv cov roj turbines thiab chav boilers.
Lub fabricability ntawm NCF800 yog lwm qhov zoo dua. Nws tuaj yeem ua tau yooj yim los ntawm ntau yam kev tsim khoom, suav nrog casting, forging, thiab machining. Qhov no enables zus tau tej cov customized Cheebtsam nrog leej geometry thiab high-zoo finishes. Tsis tas li ntawd, cov hlau muaj qhov zoo weldability, yooj yim rau kev sib dhos ntawm cov qauv loj thiab kho cov khoom puas.
Zuag qhia tag nrho, NCF800 superalloys muab qhov tshwj xeeb sib xyaw ntawm qhov kub-kub tsis kam, txhua yam muaj zog, thiab fabricability. Lawv txoj kev ntseeg siab thiab kev ua tau zoo hauv cov xwm txheej hnyav ua rau lawv tseem ceeb hauv kev lag luam niaj hnub, tsav kev tsim kho tshiab thiab ua kom muaj kev ua haujlwm zoo thiab nyab xeeb ntawm ntau lub tshuab tseem ceeb.
