Wehewehe Pōkole:

ʻO Resistohm 145 a i ʻole FeCrAl 145 kahi mea hao ferritic o ka ʻohana FeCrAl, hiki ke hoʻohana ʻia a hiki i 1300°C inā he nui nā anawaena. Hiki ke hoʻohana ʻia ʻo Resistohm 145 a i ʻole FeCrAl 145 no nā pale ʻana i nā umu uila no nā ʻoihana seramika, kemika a me ka metallurgic, a no nā noi āpau kahi e pono ai ke hoʻopili i ka mahana kiʻekiʻe loa o ka hoʻohana ʻana. ʻOi aku ka maikaʻi o ke ola o Resistohm 145 ma mua o nā NiCr inā he lewa e loaʻa ana ka sulfur a ʻoi aku hoʻi inā he oxidizing lākou. ʻO ka mea like ma Kina ʻo 0Cr21Al6Nb me ka resistivity like o 1.45μΩ/m ma 20ºC. ʻO ka ʻāpana hoʻomehana pale no nā mea hoʻomehana umu a me nā noi hana wela ʻē aʻe. Hoʻouna pinepine ʻia ka ʻāpana i ke kūlana ʻōwili anu me ka ʻili honua. Nā ʻano: 1. Paʻa maikaʻi loa 2. Kū'ē maikaʻi loa i ka corrosion i ka hapa nui o nā lewa 3. Ke alakaʻi wela kiʻekiʻe 4. ʻAʻohe scaling a me nā haumia 5. ʻOi aku ka lōʻihi o ke ola o ka paipu
