Nta:
Nrog lub neej ua haujlwm ntev. Ua kom sov sai. Ua haujlwm tau zoo heev. Kub sib xws. Siv tau ntsug. Thaum siv rau hauv qhov ntsuas hluav taws xob, tsis muaj cov khoom tsis muaj zog. Nws yog ib qho hlau hluav taws xob tiv thaiv ib puag ncig. Thiab lwm txoj hauv kev rau cov hlau nichrome kim. Yuav kho tau raws li cov neeg siv khoom xav tau.

FeCrAl alloys yog cov yam ntxwv los ntawm kev tiv taus oxidation zoo heev thiab kev ruaj khov zoo heev ua rau lub neej ntev.

Lawv feem ntau yog siv rau hauv cov khoom siv hluav taws xob hauv cov cub tawg thiab cov khoom siv hauv tsev.

Fe-Cr-Al alloy nrog lub zog tiv taus siab thiab kev pabcuam kub dua li NiCr alloy thiab kuj muaj tus nqi qis dua.
