Ibikoresho bikoreshwa mumasoko nikoreshwa ryabyo

a. Ibyuma bya karubone hamwe nicyuma kivanze: Iyo ikora amasoko, ibintu byicyuma nka silicon, manganese, chromium, vanadium na molybdenum bikunze kongerwaho ibyuma kugirango byongere ubukana numunaniro wimpeshyi kandi bigire ingaruka mbi.

b. Amasoko manini ahanini atunganywa nakazi gashyushye, ni ukuvuga, ibikoresho byamasoko bizunguruka mu nkoni ku bushyuhe bwinshi, hanyuma bigatunganywa bigakorwa ku bushyuhe bwinshi, hanyuma bikazimya amavuta cyangwa amazi kuri dogere 780 kugeza 850, hanyuma bigashyirwa kuri dogere 400 kugeza kuri 500.

c. Amasoko mato yabanje gufatanwa, hanyuma ubukonje bukorwa, kuzunguruka hanyuma gukomera no gutwarwa, nk'insinga z'icyuma, insinga ya piyano cyangwa icyuma.

d. Umugozi wa piyano ukozwe mubyuma bya karubone (0,65 ~ 0,95%) bifite umwanda muke. Iyo diameter isanzwe itari munsi ya 1/4, ikururwa mumigozi mubushyuhe bwicyumba nyuma yo kuzimya imiti. Ifite imiterere yubukanishi, imbaraga zingana kandi zikomeye, kandi ni ibikoresho byiza byizunguruka.

e. Umugozi w'icyuma udafite ingese ukoreshwa ahantu hashobora kwangirika. Ibyuma byihuta cyane nicyuma gishobora gukoreshwa kugirango bihangane nubushyuhe bwo hejuru.

f. Carbone yibikoresho byamavuta ni 0,6 ~ 0,7% kandi igomba kuba irimo manganese. 0,6 ~ 1.0% isanzwe ikoreshwa mumasoko ya coil.

g. Amasoko yamababi akunze gukoresha 0.9-1.0% ibyuma bisanzwe, naho urwego rwo hejuru rukoresha ibyuma bya chromium vanadium ibyuma na silicon-manganese.
