SUJ304/ SUS304L / SUS304Cu kubadaha birta ahama Isbarbar:
SUS304 kubbadaha birta ah: waxay leedahay iska caabin daxal wanaagsan, iska caabbinta kuleylka, xoog heerkulka hooseeya iyo astaamaha farsamada, shaqeynta kuleylka wanaagsan sida shaabbinta iyo foorarsiga, ma jiro ifafaale qallafsan daaweynta kuleylka, aan magnetic. Si ballaaran ayaa loogu isticmaalay alaabada guriga (qeybta 1, 2 miisaska), armaajooyinka, dhuumaha gudaha, kululeeyaha biyaha, kululeeyaha, barkadaha qubeyska, qeybaha gawaarida, qalabka caafimaadka, qalabka dhismaha, kiimikooyinka, warshadaha cuntada, beeraha, iyo qeybaha markabka.
SUS304 Kubadaha biraha biin la'aanta ah: birta aasaasiga ah ee austenitic, tan ugu ballaaran ee la isticmaalo; caabbinta daxalka iyo u adkaysiga kuleylka; xoog heerkulka hooseeya iyo sifooyinka farsamada; Qaab-dhismeedka austenite hal-waji ah, ma laha ifafaalo sii adkeynaya daaweynta kuleylka (non-magnetic, isticmaal heerkulka -196– 800°C).
Kubadaha birta ah ee SUS304Cu: birta birta ah ee Austenitic oo leh 17Cr-7Ni-2Cu oo ah curiyaha aasaasiga ah; qaab-dhismeed heer sare ah, gaar ahaan sawir qaadista siligga iyo gabowga iska caabbinta; - isla iska caabbinta daxalka sida 304.

Mabda'a kubbadda birta ah ee birta ah:
Kubadaha birta ahama ma yihiin miridh-caddeyn, laakiin ma fududa in miridhku dhaco. Mabda'a ayaa ah marka lagu daro chromium, lakab cufan oo chromium oxide ah ayaa laga sameeyay dusha sare ee biraha, kaas oo si wax ku ool ah u xannibi kara dib-u-xiriirka u dhexeeya birta iyo hawada, si oksijiinka hawadu uusan u geli karin birta kubada, taas oo ka hortageysa Saameynta kubadaha birta ee daxala.
Heerarka Qaranka ee Shiinaha (CNS), Jaangooyada Warshadaha ee Japan (JIS) iyo Machadka Birta iyo Birta ee Mareykanka (AISI) waxay adeegsadaan saddex lambar si ay u muujiyaan xarkaha kaladuwan ee kala geddisan, kuwaas oo si ballaaran looga soo xigtay warshadaha, kuwaas oo 200 oo taxane ay yihiin chromium-nickel-manganese oo ku saleysan birta ahama austenitic, 300 taxane waa bir birta austenitic aromo chromium-nickel, 400 silsilad bir ah oo silsilad chromium ah (oo badanaa loo yaqaan birta aan lahayn), oo ay ku jiraan martensite iyo ferrite.
