304 304L 316 316L alaabta

Birta aan daxalka lahayn waa wax ku habboon daxalka u adkaysta, waxaa jira darajooyin kala duwan oo ah birta aan fiicnayn, darajooyinka birta aan fiicnayn ee ugu caansan waa 304L iyo 316L , waxaad ku kala saartaa iyaga oo kaliya adigoo eegaya iyaga.

Farqiga u dhexeeya kiimikaad ee u dhexeeya 304L iyo 316L;
Marka laga eego dhinaca kiimikaad, 304 birta aan-ka-soo-baxa ahi waxa ay ka kooban tahay 18% chromium iyo 8% nikkel halka 316 birta aan-daawaha ahi ka kooban tahay 16% chromium, 10% nikkel iyo 2% molybdenum. Molybdenum-ka ayaa lagu daraa si ay uga caawiso iska caabinta daxalka.

Codsiyada caadiga ah ee 304L birta aan lahayn:
304L steel waa nooca ugu badan ee birta aan fiicnayn, adkaysigu wuxuu ka dhigayaa 304L fududahay in la nadiifiyo, sidaas darteedna ku habboon codsiyada jikada iyo cuntada taangiyada kaydinta, weelasha cadaadiska, iyo tuubooyinka.Mid ka mid ah khasaarooyinka isticmaalka 304L birta aan fiicnayn ee ay u nugul tahay daxalka xalalka chloride, sidaas darteed way fiicantahay in la isticmaalo 316L birta ah ee mashiinnada buuxinta haddii alaabtu ay sababi karto isdhexgalka kiimikada ee birta.

Codsiyada caadiga ah ee birta 316L:
Darajada 316L waa qaabka labaad ee ugu caansan ee birta birta ah ee 316L waxaa badanaa loo isticmaalaa codsiyo badan oo warshadeed oo ku lug leh kiimikooyinka wax soo saarka, sidaas darteed inta badan mashiinnada buuxinta ee ka shaqeeya kiimikooyinka ayaa laga sameeyaa 316L bir ah.
