Answer
Ibyuma bya karubone nyinshi nka SAE 1070-1090 birashobora kwanduzwa na Hydrogene Embrittlement (HE) mugihe cyo gufata aside cyangwa amashanyarazi (urugero, zinc cyangwa plaque ya kadmium). Hydrogen hydrogène ikwirakwira mu mbibi z’icyuma, cyane cyane munsi y’imihangayiko ikabije nk'imivumba. Ibi biganisha ku gucika intege kumitwaro iri munsi yimbaraga zumusaruro. Kugira ngo ibi bigabanuke, amasoko agomba guhita akora 'guteka' akimara kuyashyiraho - mubisanzwe ku $ 375 ^ \ kuzenguruka F \ pm 25 ^ \ kuzenguruka F $ byibuze amasaha 4 kugeza kuri 24 bitewe nubunini bwigice hamwe nuburemere. Kunanirwa guteka mugihe cyamasaha 1-4 yo gushiraho akenshi bivamo ibyangiritse bidasubirwaho. Kubintu bikomeye byo mu kirere, isahani ya mashini cyangwa vacuum irahitamo kwirinda hydrogène burundu.
