Jan 25, 2024
A105 is also even a forging carbon steel grade. a105 is also a material code, belongs to the special steel, is a kind of cold forging steel. a105 is a kind of low carbon steel forgings, and 20 steel similar. There are two standards, one is the U.S. standard "ASTMA105/A105M pipeline components with carbon steel forgings," the second is the Chinese standard "GB/T12228-2006 general valve carbon steel forgings technical conditions.
