35CrMo Alloy birta birta soo saaraha iibka dammaanadda
35CrMo waa lambarka sifaynta ee birta qaab dhismeedka daawaha (daawaha damay iyo birta diirran), kaas oo inta badan loo isticmaalo in lagu soo saaro qaybo muhiim ah mashiinnada kala duwan ee saamaynta leh, foorarsiga iyo jeexjeexyada iyo culeyska sare. Koodhka dhijitaalka ah ee midaysan ee 35CrMo alloy qaabdhismeed bir ah (alloy demayn iyo bir dabcay) waa a30352, iyo heerka fulinta waa GB / t3077-2015
