Icyiciro cya ASTM A514 Icyapa

ASTM A514 icyiciro A ni ubwoko bwa ASTM A514 ibyuma. Ibintu byavuzwe birakwiriye kuzimya no kurakara. Igishushanyo mbonera ku makarita yumutungo uri hepfo gereranya ASTM A514 icyiciro A na: icyuma gikozwe mucyuma kimwe (hejuru), ibyuma byose bivangwa nicyuma (hagati), hamwe nububiko bwose (hepfo).

Isahani yicyuma A514 Icyiciro A kiri munsi yicyuma cyerekana imbaraga zumusaruro mwinshi ASTM A514 / A514M.A514GrA ni icyuma gisya ibyuma hamwe no kuzimya no kugabanya ubushyuhe mugihe cyo kuzunguruka. 690Mpa kububyimba bwa mmmm 65mm, na 620 Mpa kubyimbye hejuru ya 65mm, imbaraga zingana zizaba ziri muri 760-895 Mpa. Uruganda rushobora kongera gushyushya amasahani atujuje ibyangombwa bisabwa byumutungo wa tekinike mugihe cyo kuzunguruka icyuma cyinshi cyicyuma A514GrA.Ibizamini byose byumutungo wubukanishi bizasubirwamo mugihe ibikoresho byoherejwe kugirango bisuzumwe.

Ibikoresho bya tekinike kuri A514GrA ibyuma bivanze:

Umubyimba (mm)	Tanga imbaraga (≥Mpa)	Imbaraga zingana (Mpa)	Kurambura muri ≥,%
			50mm
T≤65	690	760-895	18
65	620	690-895	16

Ibigize imiti ya A514GrA ibyuma bivangwa (Isesengura ry'ubushyuhe Max%)
