|---|---|
| EN ISO class | G/W 18 15 3 L |
| Other standards | ISO 20172: Gruppe 8.1 |
Purpose
- TIG rod version of the Cr-Ni-Mo INX 317L wire — same use on 317/317L stainless with chloride pitting resistance.
Why it works
Same alloy as INX 317L MIG, as a TIG rod (DC-, I1 gas) — fine puddle control for root passes on equipment exposed to chlorides.
Fields of application
- DIN 1.4429, 1.4438, 1.4439, 1.4583 (317/317L stainless steel).
- High-chloride environments and some acids (excluding nitric).
