SUPERMIG 385 (L904) is used for welding of ASTM 316 or similar steels, when a ferrite-free weld metal is required. Mainly used in cryogenic and nonmagnetic applications. The impact strength at low temperatures is excellent. Also used for welding 904L to ASTM 304 and 316. SUPERMIG 385 (L904) has a very good corrosion resistance to general, pitting and crevice corrosion as well as stress corrosion cracking.

Features
Alloy ER 385 (904L) is used for welding materials of similar chemical composition, which are used for fabrication of equipment and vessels for handling of sulfuric acid and many chloride containing media.
This filler metal may also find applications for joining Type 317L material where improved corrosion resistance in specific media is needed. In order to reduce the propensity for fissuring and hot cracking, the low melting constituents such as carbon, silicon and phosphorus are controlled to lower levels in this alloy.
Key Features
- Weld metal is fully austenitic and must be done with low heat input using a stringer bead technique

- Ink jet printing identification on entire length of electrode
Applications
- Pipeline segment
- Agitotors
- Rotars
- Used in fabrication of equipment and vessels for handling and storage of sulfuric acid and phosphoric acid
- Used for welding materials of similar chemical composition (Type 904L)
