Standard for forgings of A105 material flanges

Thread Content

What should be the forging standard for flange forgings made of A105 material? For example, the standard for forgings made of 20# material is NB/T47008-2017

A105 is the standard, ASTM A105 «Carbon steel forgings for piping components».

It depends on which flange design standard you choose. If GB, HG, or JB flange standards are chosen, then the forgings standard for A105 can be specified as GB/T 12228, since GB/T 12228 already includes A105 within it. If the SH flange standard is chosen, the forgery standard for A105 remains the American standard ASTM A105/A105M.

The American standard material is ASTM A105, while the Chinese standard is GB/T 12228
