Classification
| AWS class | ER 385 |
|---|---|
| EN ISO class | G/W 20 25 5 Cu L |
| Material no. (W.-Nr.) | 1.4519 |
Purpose
- TIG rod version of the super-austenitic INX 385 wire — same cryogenic -196°C service and corrosion resistance to 350°C.
Why it works
Same alloy as INX 385 MIG, as a TIG rod (DC-, I1 gas) — fine puddle control for root passes on high corrosion-demand equipment.
Fields of application
- DIN 1.4500, 1.4505, 1.4506, 1.4536, 1.4539 (super-austenitic Cr-Ni-Mo-Cu steel).
- Joining these steels to unalloyed or low-alloy steel.
