Insimbi ye-ASTM A871 / A871M

Ukucaciswa kwe-ASTM A871 ukucaciswa okujwayelekile kwamapuleti ensimbi anesakhiwo esinengxubevange ephezulu enamandla amakhulu anokumelana nokugqwala komkhathi asetshenziswa ezakhiweni zamashubhu nezigxobo. Amabanga 60 kanye ne-65 atholakala ezimeni ezigoqelwe, ezijwayelekile, noma ezicishiwe neziqinile njengoba kudingeka ukuze kuzuzwe izakhiwo zemishini ezishiwo.

Imininingwane:
Ubukhulu: 3mm-150mm
Ububanzi: 30mm-4000mm
Ubude: 1000mm--12000mm
Okujwayelekile: ASTM EN10025 JIS GB

I-A871 Grade 65 ingase ihlinzekwe njengegoqwe, ijwayelekile noma icinywe futhi iqiniswe.
