ASTM A871 / A871M intsimbi

Ukucaciswa kwe-ASTM A871 yinkcazo esemgangathweni yomgangatho ophezulu we-alloy low-alloy metal structural plates kunye nokumelana nokubola kwe-atmospheric esetyenziswa kwizakhiwo ze-tubular kunye nezibonda. AmaBanga 60 kunye nama-65 ayafumaneka kwiimeko eziqengqelekayo, eziqhelekile, okanye ezicinyiweyo nezipholileyo njengoko kufuneka ukuphumeza iipropati ezichaziweyo zoomatshini.

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

I-A871 yeBakala 65 inokubonelelwa njenge-rolled, iqheleke okanye icinywe kwaye ipholile.
