Classification
| AWS class | ER 308LSi |
|---|---|
| EN ISO class | G/W 19 9 L Si |
| Material no. (W.-Nr.) | 1.4316 |
| Other standards | ISO 20172: Gruppe 8.1 · TÜV Kennblatt 1000: Gruppe 29 |
Purpose
- TIG rod version of the low-carbon INX 308LSi wire — same cryogenic-to-+350°C service on austenitic steels.
Why it works
Same alloy as INX 308LSi MIG, as a TIG rod (DC-, I1 gas) — fine puddle control for root passes and thin sections in cryogenic service.
Fields of application
- DIN 1.4301, 1.4306, 1.4311, 1.4319, 1.4550, 1.4551, 1.4552 (AISI 304/304L/321/347).
- Cryogenic service down to -196°C.
