Q355B icyuma

Icyuma cya Q355B nicyuma gike cyane-icyuma gikomeye. Isahani ya Q355B ifite imikorere yubukorikori nziza, imikorere yubushyuhe buke, hamwe na plastike nziza hamwe no gusudira. Q355B ibyuma bikoreshwa mugukora ibikoresho biciriritse kandi bito, igitoro cya peteroli, imodoka, crane, imashini zicukura amabuye y'agaciro, sitasiyo, ikiraro, nibindi.

Ibigize imiti ya Q355B icyuma:
C≤0.24, Si≤0.55, Mn≤1.6, P≤0.035, S≤0.035, Ni≤0.3; Cr≤0.3, N≤0.0012

Ibikoresho bya tekinike ya Q355B icyuma:
Gutanga imbaraga≥355, imbaraga zingana: 470-630, Akv≥34.

Icyuma cya Q355B gikoreshwa cyane mubuhanga, imashini zicukura amabuye y'agaciro, ibiraro, ibinyabiziga, amato, ubwubatsi, ubwato bwumuvuduko, ibikoresho bidasanzwe, nibindi.
