Ocr21al4 Fecral Hluav Taws Xob Resistance Heating Hlau
OCr21Al4 yog ib yam khoom siv ntawm Fe-Cr-Al alloy.
FeCrAl alloy muaj cov yam ntxwv ntawm kev ua haujlwm siab, tsis tshua muaj qhov kub thiab txias coefficient, kev ua haujlwm siab kub, zoo tiv thaiv oxidation thiab tiv thaiv corrosion nyob rau hauv kub.
Nws yog dav siv nyob rau hauv industrial furnace, khoom siv hauv tsev, kev lag luam rauv, metallurgy, machinery, aircraft, automotive, tub rog thiab lwm yam industries ua cua sov ntsiab thiab kuj ntsiab.
FeCrAl alloy series: OCr15Al5, 1Cr13Al4, 0Cr21Al4, 0Cr21Al6, 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2, thiab lwm yam.
