GB/T 983 E385-16 AWS A5.4 E385-16
Suitable for welding stainless steels used in acid and some chloride-containing media, such as 904L stainless steel.
Rutile-coated Cr20Ni25Mo5 stainless steel electrode with excellent welding process performance. The electrode features stable arc, minimal spatter, aesthetically pleasing weld bead formation, and resistance to reddening of the coating. The deposited metal exhibits good resistance to acid, formic acid, acetic acid media pitting corrosion, and chloride ion corrosion.
AC, DC reverse polarity (AC, DC+), with DC reverse polarity recommended.

1. Drying requirement: Electrodes must be baked at 300°C for 1 hour before use and used immediately after baking.
2. When using AC welding, spatter is greater, the coating is prone to reddening, and penetration is shallower. Therefore, DC reverse polarity welding is recommended.
3. Use low current and short arc welding as much as possible during welding, with minimal oscillation amplitude.
