Q275 icyapa

Icyuma cya Q275 nicyuma cyububiko bwa karubone, imbaraga nyinshi, plastike nziza nogukora neza, imikorere myiza yo gusudira, ibice bito birashobora kuzimya no gukomera, ahanini bikoreshwa mugukora ibice bisabwa cyane, nkibikoresho na shitingi. , amasoko, urufunguzo, bolts, imbuto, ibyuma byigice cyimashini zubuhinzi, iminyururu ya convoyeur hamwe.

Q275 icyuma gisa nicyuma gihwanye: gihuye nu kirango cyabayapani JIS: SS490
Umuryango mpuzamahanga ushinzwe ubuziranenge:
E275A
Bihuye nikirango gishaje: A5

Ibigize imiti (igice kinini) cya Q275 icyuma (%)
