4. Menene bambanci tsakanin ASTM A709 da ASTM A36?
ASTM A709 yana da ƙarfi mafi girma, mafi ƙarfi, da kuma zaɓin halayen yanayi.
ASTM A36 ƙarfe ne na carbon na yau da kullun, galibi don aikace-aikacen gine-gine gabaɗaya, ba a inganta shi don gadoji ko mahalli masu wahala ba.
5. Ta yaya ake gwada farantin ƙarfe na ASTM A709?
Gwaje-gwajen tensile don tabbatar da yawan amfanin ƙasa da ƙarfin ƙarshe
Gwaje-gwajen tasirin Charpy don tauri a ƙananan yanayin zafi
Binciken kimiyya don tabbatar da abun da ke ciki na alloy
Duban lanƙwasa da girma
6. Me yasa za a zaɓi farantin ƙarfe na ASTM A709?
Babban ƙarfi don rage nauyi
Kyakkyawan aikin walda da ƙira
Zaɓin zaɓi na yanayin yanayi don dorewa na dogon lokaci
Ya dace da yanayin zafi mai ƙarancin zafi da kuma yanayin damuwa mai tsanani
