Ulwazi lwemveliso Ukwakhiwa kweekhemikhali kunye nepropathi yeMechanical

Ulwazi lwemveliso

I-ASTM A709 yiNgcaciso yoMgangatho weStructural Steel yeeBridges kwaye ibandakanya ikhabhoni, i-high-high-high-high-alloy alloy, kunye ne-alloy ecinyiweyo kunye ne- tempered alloy steels esetyenziswa njengeepleyiti zesakhiwo ekwakhiweni kweebhulorho. I-Gnee ibonelela ngala mabakala amahlanu alandelayo e-A709; 36, 50, 50W, HPS 50W kunye ne-HPS 70W. Amabanga amathathu emozulu ye-50W, HPS 50W, kunye ne-HPS 70W bane-ASTM G101 ephuculweyo ye-Atmospheric Corrosion Resistance Index ye-≥6.0.
