440c saxan bir ah oo aan lahayn
Sharaxaad Gaaban:
440C bir aan lahayn waa bir-kaarboon-martensitic ahama-sare. Waxay leedahay xoog sare, iska caabin daxalka dhexdhexaad ah, iyo engegan wanaagsan oo xidho iska caabin.
440C Taarikada Birta Aan-la-aanta ah ee Hal joogsiga Bandhigga Adeegga:
Marka ay timaado saxan bir ah oo ah 440C, waxa ay tilmaamaysaa bir fidsan oo laga sameeyay 440C birta aan lahayn. Taarikadan waxaa inta badan loo isticmaalaa wax soo saarka iyo codsiyada warshadaha kala duwan halkaas oo heer sare ah oo adkaanta iyo iska caabin daxalka loo baahan yahay. Cabbirrada iyo qeexitaannada saxanku way kala duwanaan karaan iyadoo ku xidhan shuruudaha gaarka ah ee codsiga.440C birta aan lahayn waxay caan ku tahay awoodda kulaylka lagu daaweeyay adagaanta heerka sare ee 440 heerka, sida 440A iyo 440B. Daawaynta kulaylku waxay kor u qaadi kartaa sifooyinka farsamada, oo ay ku jiraan qallafsanaanteeda iyo xirashada caabbinta.
