904L xaashida birta aan lahayn

Super austenitic ahama bir ah (904L saxan bir ahama) waa bir austenitic ahama leh oo leh kaarboon aad u hooseeya iyo alloying, kaas oo leh iska caabin aad u wanaagsan oo daxalka ah oo ku dhex milma sulfuric acid waxaana loogu talagalay bay'ada daxalka adag. Waxa uu leeyahay maaddo chromium sare ah iyo nikkel ku filan, marka lagu daro naxaasta waxa ay siinaysaa caabbinta aashitada oo xooggan, gaar ahaan iska caabin badan oo ay u leedahay daxalka chloride-ka iyo dildilaaca daxalka stress, mana fududa in ay yeeshaan dhibco iyo dildilaacyo. Iska caabbinta godadku wax yar bay ka fiican tahay darajooyinka birta kale. Waxay leedahay mashiin wanaagsan iyo alxan, waxaana loo isticmaali karaa weelasha.

904L xaashida birta aan lahayn waxaa lagu yaqaanaa caabbinta heer sare ah ee noocyada kala duwan ee daxalka, oo ay ku jiraan daxalka guud, dalool, daxalka dillaaca, iyo dildilaaca daxalka. Waxa ku jira nikkel-sare iyo molybdenum-ka ayaa ka qaybqaata iska caabinta daxalka ee wanaagsan. Intaa waxaa dheer, 904L waxay leedahay alxanka wanaagsan, taas oo sahlaysa in la abuuro qaabab iyo qaabab adag.

Habka wax soo saarka ee xaashida birta ah ee 904L waxay ku lug leedahay dhalaalidda alaabta ceeriin ee foornada korantada, ku tuurista birta dhalaalaysa ee jeexjeexyada ama dhejiska, kuleyl kuleyl kuleyl ah dhumucdii la rabay, ka dibna qabow-rogid si loo gaaro cabbirka ugu dambeeya iyo dhammaadka dusha sare. Walaxda waxa kale oo laga yaabaa in ay maraan nuugista xalalka iyo deminta biyaha si loo hagaajiyo sifooyinka farsamada iyo iska caabinta daxalka.
