Birta aan la-qabin 409

409 steel waa bir Ferritic ah oo bixisa sifooyin farsamo oo wanaagsan iyo iska caabin daxalka heerkulkiisu sarreeyo. Waxaa caadi ahaan loo tixgaliyaa sidii bir aan lahayn chromium, oo leh codsiyada nidaamka qiiqa baabuurta iyo codsiyada u baahan alxanka.

409 bir ah ayaa sidoo kale lagu heli karaa qaabab aad loo xasiliyay, sida darajooyinka S40930, S40920 iyo S40910. Xasiloonida darajooyinkan waxaa bixiya joogitaanka niobium, titanium, ama labadaba, ee ka kooban biraha.

Darajooyinka Beddelka ah ee suurtogalka ah

Darajo	Guryaha
3CR12	Si fudud alxanka iyo iska caabbinta daxalka wanaagsan. Qaybaha culus ayaa si fudud loo heli karaa marka la barbar dhigo 409.
304	Iska caabbinta kulaylka sare iyo iska caabinta daxalka. Fasalka 304 waa qaali.
321	Iska caabbinta kulaylka wanaagsan marka loo eego 304 ama 409.
Bir aluminium ah	Ka jaban darajada 409 birta aan dahsoon, laakiin adkeysi yar u leh gaaska qiiqa.
