440c Bir aan Daxal lahayn oo Fidsan
Sharaxaad Gaaban:
Baararka Fidsan ee UNS S44000, Baararka Fidsan ee SS 440, Baararka Birta aan Lahayn ee 440 ee Fidsan, Alaab-qeybiye, Soo-saare iyo Dhoofiye Shiinaha.
Biraha aan lahayn birta waa bir aad u badan oo leh iska caabin daxaleed oo sare marka loo eego biraha kale sababtoo ah joogitaanka xaddi badan oo chromium ah. Iyada oo ku saleysan qaab-dhismeedkooda crystalline, waxaa loo qaybiyaa saddex nooc sida birta ferritic, austenitic, iyo martensitic. Koox kale oo bir ah oo aan lahayn birta waa bir aad u adag oo roobka. Waa isku-darka biraha martensitic iyo austenitic. Bir aan lahayn birta 440C waa bir aan lahayn birta martensitic oo kaarboon sare leh. Waxay leedahay xoog sare, iska caabin daxaleed dhexdhexaad ah, iyo adkeysi wanaagsan iyo iska caabin xirasho. Darajada 440C waxay awood u leedahay inay gaarto, ka dib daaweynta kulaylka, xoogga ugu sarreeya, adkaanta iyo iska caabinta xirashada dhammaan biraha aan lahayn birta. Waxyaabaha ay kaarboonka aad u sarreeyaa ayaa mas'uul ka ah sifooyinkan, kuwaas oo ka dhigaya 440C mid si gaar ah ugu habboon codsiyada sida biraha kubbadda iyo qaybaha waalka.
