304H;
Macluumaadka aasaasiga ah
Tuubooyinka kuleyliyaha ayaa asal ahaan loo isticmaalaa in lagu wareejiyo kulaylka hal dhibic oo taagan una gudbiya kulaylka u dhexeeya wax ka badan hal dareere.Sariflayaashan waxaa laga heli karaa qaboojiyaha iyo warshadaha baabuurta halkaas oo uu jiro heerkul sare iyo jawi kuleyl.Caadi ahaan, sariflayaasha kuleylku wareejinta waxa ay ku dhacdaa iyada oo la marsiinayo dareeraha tubooyinka isbar-barya.qalabyo kala duwan ayaa loo isticmaalaa samaynta tubooyinkan.Laakiin birta ugu waxtarka badan uguna faa'iido badan waa birta aan lahayn sababtoo ah sifooyinkeeda wanaagsan iyo isku-dheelitirka kiimikada.
Birta aan-dhalatada lahayn waxay ka kooban tahay qadar yar oo chromium ah taas oo marka ay kordhiso hantida iska caabinta birta ay sidoo kale kordhiso.Joogitaanka molybdenum ee birta ayaa kor u qaadaysa xooggeeda iyo sifooyinka kale.304H waa darajo sare oo kaarboon ah oo aan birta lahayn kaas oo ka door bidaaya darajooyinka kale ee SS sababtoo ah hantidiisa iyo dulqaadka deegaanka balaadhan.Darajada 304H waxay bixisaa xoog xajin sare leh, sifooyin gurguurta oo gaagaaban oo aad u fiican iyo sifooyin iska caabin heer sare ah.Tani sidoo kale waa sababta kor loogu qaadayo darajadan ee soo saarista tuubooyinka kulaylka.
Isagoo ka hadlaya sifooyinka jirkiisa, SS 304H waxay bixisaa iska caabin heer sare ah oo u adkaysta daxalka, iska caabinta deegaanka chloride, iska caabinta dildilaaca daxalka iyo iska caabbinta daxalka ee heerkul sare iyo cadaadis.
