Classification
| AWS class | E 8010 - G |
|---|---|
| EN ISO class | E Z 46 3 Mo C 21 |
Purpose
- Mo-alloyed cellulosic electrode for high-strength low-alloy steel pipeline (AWS E 8010-G, EN ISO E Z 46 3 Mo C 21), suited to sour-gas service.
Why it works
Combines FERVEO STL 420C2's Mo alloying with an additional mechanical-strength step, for pipeline joining in all positions with particular suitability vertical-down.
Fields of application
- Joining of high-strength low-alloy steel gas and oil pipeline, with sour-gas service applications (HIC test per NACE TM-0284).

Advantages
- Suited to sour gas per the NACE TM-0284 HIC test, at a higher mechanical-strength step than FERVEO STL 420C2.
Limitations
- For the same strength step with nickel instead of molybdenum alloying, see FERVEO STL 460C3 1Ni.
