Ku $ 400 ^ {\ umuzenguruko} F $, SAE 1070 ibyuma bya karubone bitangira gutakaza umujinya kandi bizagira uburuhukiro bukomeye (gutakaza imbaraga za 'clinging') mugihe runaka. Ibi birashobora gutuma impeta irekura muri ruhago, biganisha ku kunyeganyega no kwambara. Ibinyuranye, 17-7PH (Imiterere CH900) ihagaze neza kugeza $ 650 ^ {\ umuzenguruko} F $. Microstructure ya 17-7PH yimvura igwa irinda ingendo ya dislocation ijyanye nubushyuhe bwumuriro kuri ubu bushyuhe. Kubwibyo, kuri moteri iyo ari yo yose cyangwa umuyaga uherekejwe na porogaramu aho ubushyuhe burenga $ 350 ^ {\ umuzenguruko} F $, 17-7PH nuguhitamo itegeko kugirango impeta igumane ubunyangamugayo kandi igume yicaye.
