In birta laba-laabka ah (DSS), wajiga austenite iyo wejiga ferrite waxay ku xisaabtamaan kala badh qaab dhismeedka xalka adag, waxayna leeyihiin astaamo qaab-dhismeed laba weji ah.Ma aha oo kaliya in ay sii haysato sifooyinka birta birta ah ee ferritic, sida kulaylka kulaylka weyn, isugeynta fidinta tooska ah ee yar yar, iska caabinta daxalka iyo daxalka dillaaca, iyo daxalka chloride stress, laakiin sidoo kale waxay leedahay adayg wanaagsan, heerkulka kala-guurka jaban hooseeya iyo iska caabinta daxalka intergranular ee austenitic ahama.Waxqabadka wanaagsan iyo faa'iidooyinka kale, waxaa si weyn loogu isticmaalaa petrochemical, daabacaadda iyo rinjiyeynta, injineernimada badda, warshadaha cuntada iyo warshadaha waraaqaha.
Iyada oo isbeddelka lagu kordhinayo cabbirka qalabka warshadaha casriga ah iyo dhimista kharashyada wax-soo-saarka, qaybo waaweyn ayaa inta badan la soo saaray iyada oo la dulsaarayo lakabyada birta aan daxalka lahayn ee duplex ee substrates-ka aluminiumka ah.
Habka dusha sare ee electroslag Strip waxaa si weyn loogu isticmaalaa wax soo saarka sababtoo ah tayada alxanka xasilloon, heerka sare ee otomatiga, iyo wax soo saarka sare.
