Baarka Birta Aan Daxalka Ahayn ee 403
Sharaxaad Gaaban:
Birta aan lahayn 403 waa bir aan lahayn xinjirowga martensitic oo leh kaarboon aad u sarreeya iyo iska caabin dhexdhexaad ah oo daxalka ah.
Kormeerka UT ee otomaatiga ah ee 403 wareeg ah:
403 waa bir martensitic ah, sifooyinkeedana waxaa si weyn u saameyn kara daaweynta kulaylka. Waa la adkeyn karaa oo la hagaajin karaa si loo gaaro sifooyinka farsamada ee la rabo. In kasta oo birta aan lahayn 403 ay bixiso iska caabin dhexdhexaad ah oo daxalka ah, haddana uma adkaysto daxalka sida birta aan lahayn ee austenitic sida 304 ama 316. Waxay ku habboon tahay codsiyada deegaannada daxalka khafiifka ah. Birtan waxay gaari kartaa heerar adag oo sare ka dib daaweynta kulaylka, taasoo ka dhigaysa mid ku habboon codsiyada halkaas oo adkeysiga iyo iska caabinta xirashada ay muhiim yihiin. Waxay leedahay alxan cadaalad ah, laakiin inta badan waa loo baahan yahay kuleylinta kahor, daaweynta kulaylka ka dib alxanka ayaa laga yaabaa inay lagama maarmaan noqoto si loo yareeyo khatarta dildilaaca.
