| EN ISO class | ~G/W GZ 21 33MnNb |
| Material no. (W.-Nr.) | 1.4850 |
Purpose
- TIG rod version of the heat-resistant Cr-Ni-Mn-Nb INX 800 wire — same 1050°C service.
Why it works
Same alloy as INX 800 MIG, as a TIG rod (DC-, I1 gas) — fine puddle control for root passes on heat-resistant castings.
Fields of application
- DIN 1.4859, 1.4876, 1.4958, 1.4959 (equivalent heat-resistant castings).
