A105 flange refers to a flange made of A105, which belongs to the American ASTM standard number, and A represents ordinary carbon structural steel. Standard name: Carbon steel forgings for pipe parts. Because this standard only specifies one type of carbon steel forgings, A105 is also considered a carbon steel grade for forgings. A105 is also a material code, which belongs to special steel, which is a kind of cold forged steel. A105 is a low carbon steel forging, similar to 20 steel. There are two standards, one is the American standard "ASTM A105/A105M Carbon Steel Forgings for Piping Components", and the other is the Chinese standard "GB/T12228-2006 General Valve Carbon Steel Forgings Technical Conditions".
Composition :
