ASTM A871 / A871M simbi

Iyo ASTM A871 yakatarwa ndiyo yakajairwa dhizaini yepamusoro-yakadzika-yakadzika-alloy structural simbi mahwendefa ane atmospheric corrosion resistance anoshandiswa mu tubular zvimiro nemapango. Magiredhi 60 uye 65 anowanikwa mune se-yakakungurutswa, yakajairwa, kana kudzimwa uye kudzikamisa mamiriro ekutumira sezvinodiwa kuti uwane yakatsanangurwa michina zvivakwa.

Izvo zvakatemwa:
Ukobvu: 3mm--150mm
Upamhi: 30mm--4000mm
Kureba: 1000mm--12000mm
Standard: ASTM EN10025 JIS GB

A871 Giredhi 65 inogona kupihwa se-yakakungurutswa, yakajairwa kana kudzimwa uye kudzikamiswa.
