A709 Grade 50S pā kila

ʻO A709 Grade 50S kila kila he ikaika kiʻekiʻe haʻahaʻa haʻahaʻa structural carbon steel i hoʻohana ʻia i ke kūkulu ʻana i nā papahana alahaka.

Hoʻohālikelike A709 Gr.100, a me A709 Gr.50w papa, A709 Gr.50S i ka haʻahaʻa hua ikaika ma 345Mpa i maʻamau. A 709 Gr.50S noi pepehi a semi-pepehi ma ka hana.
Hāʻawi ʻia ʻo Gnee steel A709 Gr.50S i nā makahiki he nui ma nā papahana alahaka ʻāina ʻo Kina. Loaʻa iā mākou ka nui o nā kumukūʻai ma A709 Gr.50S no ka makemake wikiwiki i kā mākou mea kūʻai. I kēia manawa, ke hoʻonui nei mākou i kā mākou mākeke kila o ka'āina'ē ma nā papa kila A709 Gr.50S.

No ka waiwai hou aku ma ka pā kila A709 Gr.50S, e ʻoluʻolu e nānā iā lākou ma ka hahai ʻana;
