420 Bir-Flat Bir ah
Sharaxaad Gaaban:
Din 1.4034 SS 430 baararka fidsan, SS UNS S42000 baararka fidsan, birta aan fiicnayn 420 bar bar, 420 ahama birta qabow sawiran baararka alaab-qeybiyeyaasha Shiinaha.
Fasalka 420 birta aan la taaban karin waa bir kaarboon-sare oo leh ugu yaraan chromium ka kooban 12%. Sida birta kale ee kale, fasalka 420 waxa kale oo lagu adkeyn karaa daawaynta kulaylka. Waxay bixisaa ductility wanaagsan xaaladdeeda la jeexjeexay iyo guryaha iska caabbinta daxalka aad u fiican marka birta la sifeeyo, oogada dhulka la dhigo ama la adkeeyo. Darajadani waxay leedahay engegnaanta ugu sareysa - 50HRC - marka lagu daro dhammaan darajooyinka birta aan la taaban karin ee leh 12% chromium.
