ASTM A588 / A588M intsimbi

Inkcazo esemgangathweni yomgangatho ophezulu we-low-alloy structural iron, ukuya kwi-50 ksi [345 MPa] inqanaba elincinci lesivuno, kunye nokumelana nokubola kwe-atmospheric.
I-ASTM G101 i-Corrosion Resistance Index efunekayo kufuneka ibe ≥ 6.0. Ukongeza kwisicelo esiqhelekileyo kwiibhulorho ezidityanisiweyo kunye nezakhiwo, iinkcukacha zikwasetyenziswa ngokuqhelekileyo kwiimoto zikaloliwe zabahambi.

Iinkcukacha:
Ukutyeba: 3mm--150mm
Ububanzi: 30mm--4000mm
Ubude: 1000mm--12000mm
Umgangatho: ASTM EN10025 JIS GB

Ukusetyenziswa okuqhelekileyo
Le ntsimbi inokushiywa ingapeyintwayo isenza isicelo esifanelekileyo kuquka iibhulorho, izakhiwo, kunye nezinye izakhiwo.
