Amakuru

Ibikoresho: Ibyuma byamasoko (65Mn, 60Si2Mna), ibyuma bitagira umwanda (304316L), ibyuma bitagira umwanda (420)

Igice: Ibice igihumbi

Gukomera: HRC: 44-51, HY: 435-530

Kuvura hejuru: Kwirabura

Ibikoresho: ibyuma bya Manganese (65Mn, 1566)

Ibiranga ibikoresho: Nicyuma gikoreshwa cyane nicyuma cya karubone, gifite imbaraga nyinshi, gukomera, gukomera, no gukomera ugereranije nicyuma 65. Uburemere bukomeye bwa diameter ni 30-50mm mumazi na 16-32mm mumavuta. Ifite ibyiyumvo byo gushyuha cyane kandi ikunda kurakara mugihe cyo kuvura ubushyuhe, kandi ikunda gucika mugihe cyo kuzimya amazi. Kuzimya amavuta muri rusange bikoreshwa. Kuzimya amazi birakwiriye kubunini burenze 80. Gukonjesha amavuta: Nyuma yo gufunga, ubushobozi bwo gukata nibyiza, ariko plastike yo guhindura imbeho ikonje ni mike, kandi imikorere yo gusudira ni mibi. Muri rusange ibyuma bikoreshwa nyuma yo kuzimya no gushyuha mubushyuhe bwo hagati. 3-16
