35CrMo alloy ibyuma bikora uruganda rukora garanti yo kugurisha
35CrMo numubare wihariye wibyuma byubatswe byubatswe (ibyuma bizimya kandi byuma), bikoreshwa cyane mugukora ibice byingenzi mumashini atandukanye bigira ingaruka, kunama no gutemba hamwe nuburemere bwinshi. Kode ihuriweho na 35CrMo alloy ibyuma byubaka (alloy yazimye kandi ifite ubushyuhe) ni a30352, naho urwego nyobozi ni GB / t3077-2015
