440c Bir-Flat Bir ah
Sharaxaad Gaaban:
UNS S44000 baararka fidsan, SS 440 baararka fidsan, birta aan daahin 440 iibiye baararka fidsan, soo saaraha iyo dhoofiyaha Shiinaha.
Biraha birta aan lahayni waa biro-daawaha sare leh kuwaaso iska caabbinta daxalka sare leh marka loo eego birta kale sababtoo ah joogitaanka xaddi badan oo chromium ah. Iyada oo ku saleysan qaab dhismeedka crystalline, waxay u qaybsan yihiin saddex nooc sida birta birta ah, austenitic, iyo martensitic. Koox kale oo ka mid ah birta aan-ka-soo-baxa lahayn ayaa ah birta roobka-adag. Waxay yihiin isku-dhafka birta-martensitic iyo austenitic. Fasalka 440C birta aan lahayn waa bir aan lahayn kaarboon martensitic sare. Waxay leedahay xoog sare, iska caabin daxalka dhexdhexaad ah, iyo engegan wanaagsan oo xidho iska caabin. Fasalka 440C wuxuu awood u leeyahay inuu gaaro, daaweynta kulaylka ka dib, xoogga ugu sarreeya, qallafsanaanta iyo xirashada caabbinta dhammaan Alloysyada aan nadiifka ahayn. Kaarboonka aadka u sarreeya ayaa mas'uul ka ah sifooyinkan, kaas oo ka dhigaya 440C si gaar ah ugu habboon codsiyada sida kubbadaha iyo qaybaha valve.
