Q345B Carbon Round Bar
Q345B asye wonn bar se yon kalite asye, ki konpoze de Q + nimewo + senbòl klas bon jan kalite + senbòl deoxygenation metòd. pèfòmans, pèfòmans soude ak pèfòmans machinability. Lajman itilize nan pon, machin, bato, bilding, veso presyon, elatriye Q kanpe pou sede a nan materyèl sa a, ki te swiv pa 345, se sa ki, valè a sede nan materyèl sa a, nan apeprè 345. Epi yo pral ogmante ak epesè nan materyèl la epi fè valè sede li diminye.
