"Q" se premye lèt òtograf Chinwa "Qufu dian", ki vle di Yield Point.
"235" refere a fòs sede minimòm 235 MPa teste ak dyamèt ba asye oswa epesè plak Mwens pase oswa egal a 16mm.
A, B, C ak D reprezante bon jan kalite.
Karakteristik ak Aplikasyon
Q235 asye gen bon plastisit, severite ak soudabilite, osi byen ke yon fòs modere, bon pèfòmans koube frèt. Materyèl Q235 se souvan woule nan baton fil oswa asye wonn, asye kare, asye plat, asye ang, travès mwen, asye chanèl, lòt seksyon ak plak asye. Pwodwi sa yo lajman itilize nan konstriksyon ak jeni estrikti soude, fè ba asye oswa bati bilding faktori, gwo fò tou won transmisyon vòltaj segondè, pon, machin, chodyèr, resipyan, elatriye, epi tou yo itilize kòm yon pati mekanik ak pèfòmans mwens egzijan tankou baton mwens ensiste, konekte branch bwa, vis, nwa, ferrules, parantèz, ak kanpe, elatriye.
