FeCrAl huila 0Cr27Al7Mo2 CrAl kiʻekiʻe wela pale ʻana Alloy Kūʻē Uea
ʻO ka FeCrAl alloy he kiʻekiʻe ke kūpaʻa a me ka hoʻomehana uila. Hiki i ka Fecral alloy ke hiki i ke kaʻina hana o 2192 a 2282 F, e pili ana i kahi mahana kū'ē o 2372F.
I mea e hoʻomaikaʻi ai i ka hiki ke anti-oxidation a hoʻonui i ke ola hana, hoʻohui pinepine mākou i ka hoʻohui ʻana i nā ʻāina laha ʻole i ka alloy, e like me La + Ce, Yttrium, Hafnium, Zirconium, etc.
Hoʻohana maʻamau ia i ka umu uila, nā kīʻaha kīʻaha kiʻekiʻe, nā mea hoʻomehana quartz tube, nā mea pale, catalytic converter, nā mea hoʻomehana etc.
0Cr27Al7Mo2 Nominal Analysis
27.00 Cr, 7.00 Al, 2.00 Mo, Bal. ʻO Fe
ʻO ka wela hana mau loa: 1400 C.
Anawaena uwea: 0.5 ~ 12mm
Ka wela hehee: 1520 C
Ke kū'ē uila: 1.53 ohm mm2/m
Ua hoʻohana nui ʻia e like me nā mea hoʻomehana i nā umu ahi a me nā kiln uila.
He ʻuʻuku ka ikaika wela ma mua o nā alloys Tophet akā ʻoi aku ka kiʻekiʻe o ka helu heheʻe.
