Classification
| AWS class | ER 316LSi |
|---|---|
| EN ISO class | G/W 19 12 3 L Si |
| Material no. (W.-Nr.) | 1.4430 |

Purpose
- TIG rod version of the low-carbon INX 316LSi wire — same cryogenic-to-+400°C service on corrosion-resistant stainless.
Why it works
Same alloy as INX 316LSi MIG, as a TIG rod (DC-, I1 gas) — fine puddle control for root passes and thin sections in cryogenic service.
Fields of application
- DIN 1.4401, 1.4404, 1.4571, 1.4580, 1.4583 (AISI 316/316L/316Ti).
- Cryogenic service down to -196°C.
