What does "G" stand for?

牛丫丫

Everybody, you may notice there are some welding materials with suffix G, eg. ER70S-G, so please guess what does the "G" really stand for? Which word can be used to describe the characteristic accurately?

You see note f) of table 1 in SFA 5.18,you will find the answer.
Chemical requirements are not satified but there shall be no intensional addition of Ni，Cr,Mo,or V.Compositon shall be reported.Requirements are those agreed to by the purchaser and the supplier.

牛丫丫

yes, the chemical requirements are not specified, it is open to the purchaser.

牛丫丫
