A105 is the American ASTM standard number, and A stands for ordinary carbon structural steel. Standard name: Carbon steel forgings for pipe parts. Because this standard only specifies a carbon steel forging, A105 is also a forging carbon steel grade. A105 is also a material code, belonging to special steel, is a 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 pipeline components", and the second is the Chinese standard "GB/T12228-2006 general valve carbon steel forgings technical conditions".
