SUS410 / SUS420J2 / SUS430 kuul bir ahama Isbarbar dhig：
SUS410: Martensite wuxuu matalaa heerka birta, oo leh awood sare iyo adkaansho sare (magnetic); caabbinta daxalka liidata, oo aan ku habboonayn in lagu isticmaalo bey'adaha si ba'an u waxyeelleeya; maadada C hooseysa, shaqeynta wanaagsan, iyo dusha sare waxaa qallajin kara daaweynta kuleylka.
SUS420J2: Martensite wuxuu matalaa heerka birta, oo leh awood sare iyo adkaansho sare (magnetic); caabbinta daxalka oo liidata, habsocod xumo iyo qaab dhismeed, iyo iska caabin wanaagsan oo duug ah; waa la daaweyn karaa kuleylka si loo hagaajiyo guryaha. Waxaa si weyn loogu isticmaalaa soo saarida mindiyo, biiyaha, filtarka, taliyayaasha, iyo weelka miiska.
SUS430: Heerka fidinta kuleylka oo hooseeya, qaabeyn wanaagsan iyo u adkeysiga qiiqa. Ku habboon qalabka kuleylka u adkaysta, gubidda, qalabka guryaha, fasalka 2aad ee miiska, saxanka jikada. Qiimo jaban, shaqo wanaag ayaa badal u ah SUS304; caabbinta daxalka wanaagsan, daaweynta caadiga ah ee aan kuleylka aheyn ee birta birta ah ee adag.

Mabda'a kubbadda birta ah ee birta ah:
Kuullada biraha ahama ma aha miridh-caddeyn, laakiin ma sahlana 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 kubbadda, taas oo ka hortageysa Saamaynta birta birta daxaleysa.
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.
