A709 Gulu la 50S mbale yachitsulo

A709 Grade 50S zitsulo kalasi ndi mkulu mphamvu otsika aloyi structural carbon zitsulo ntchito pomanga mlatho ntchito.

Yerekezerani ndi A709 Gr.100, ndi A709 Gr.50w kalasi, A709 Gr.50S ili ndi mphamvu zokolola zochepa kwambiri mu 345Mpa mwachizolowezi. Zopempha za 709 Gr.50S zidaphedwa kapena kuphedwa pang'onopang'ono popanga.
Gnee steel supply A709 Gr.50S zaka zambiri ku China mapulojekiti amalatho akumtunda. Tilinso ndi masikelo ambiri mu A709 Gr.50S pakufunika mwachangu kwa makasitomala athu. Tsopano, tikukulitsa msika wathu wachitsulo kunja kwa mbale zazitsulo za A709 Gr.50S.

Kuti mudziwe zambiri mu mbale yachitsulo ya A709 Gr.50S, chonde yang'anani motsatira;
