Menya uburyo bwibanze bwo kunanirwa kwicyuma cya karubone cyamazi ahantu h'ubushuhe buhebuje udashyizeho isahani.

Uburyo bwibanze bwo kunanirwa ni Stress Corrosion Cracking (SCC) cyangwa okiside yoroshye iganisha kumyobo. Ibyuma bya karubone (SAE 1070-1090) byoroshye cyane ingese imbere yubushuhe. Gutobora bikora nkibibazo bikomeye ($ K_t $). Kuberako amasoko yumuraba akora murwego rwo hejuru (akenshi 30-50% yimbaraga zikaze), urwobo rushobora guhinduka vuba mumunaniro. Iyo ibice bitangiye, kugabanuka kwambukiranya igice biganisha ku gukwirakwira vuba kugeza igihe cy'impeshyi. Kugira ngo wirinde ibi, amasoko y'ibyuma bya karubone asanzwe arangizwa na Zinc Fosifate (amavuta yashizwemo) cyangwa Vapor Degreased hanyuma igashyirwaho amavuta yo kurwanya ruswa.
