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
- Low-carbon Cr-Ni 19/9.5 solid wire for joining and surfacing corrosion-resistant austenitic steels, tough down to cryogenic temperature.
Why it works
Low carbon (0.02%) avoids sensitization when welding — built for service from -196°C (cryogenic) up to +350°C, on the same DIN 1.4301/1.4306/1.4311/1.4319/1.4550/1.4551/1.4552 steels (AISI 304/304L/321/347 equivalents).
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.
