GB/T 983 E312-16
Description：
E312-16 is used for welding type 316L or 318 stainless steels. It has a maximum of .04% carbon content in the weld metal, which reduces the possibility of carbine precipitation and consequent intergranular corrosion. This electrode is widely used in the welding of chemical equipment.

Note:
1.The electrodes should be baked 1 hours in 300-350℃ before using.
2.Welding in short arc,and swing scope should not excess 2.5 times of the electrode diameter.
