Birta aan la-qabin 904L

904L ahama birta waa bir aan xasilin oo austenitic ahama leh oo leh kaarboon yar. Birtan aan lahayn alwaaxyada sare waxa lagu daraa naxaas si ay u wanaajiso iska caabbinta aysiidhyada yaraynta xoogan sida sulfuric acid. Birtu waxay sidoo kale adkaysi u leedahay dildilaaca daxalka iyo daxalka dillaaca. 904L waa non-magnetic, oo waxay bixisaa qaab aad u fiican, adkaanta iyo weldability.904L ka kooban xaddi badan oo ah maaddooyinka qaali ah, sida molybdenum iyo nikkel. Maanta, inta badan codsiyada ka shaqeeya darajada 904L waxaa lagu bedelay bir aan qaali ahayn oo duplex ah 2205.
