Bohler Fox E 347 H (Heat Resistant) Stainless Steel Stick Electrodes
The electrode is widely used in the petrochemical, chemical, and power generation industries for components subjected to high heat. It is tailored to weld niobium (Nb) or titanium (Ti) stabilized chromium-nickel (CrNi) steels, specifically where standard alternatives risk losing ductility during post-weld heat treatments (PWHT) or prolonged high-temperature exposure.
Features
- Engineered primarily for welding similar stabilised high-carbon chromium-nickel (CrNi) steels.
- This electrode is a specialised choice for welding high-alloyed, creep resistant steels used in high-stress thermal environments.
- Frequently deployed in power generation facilities, heavy boiler manufacturing, and oil/petrochemical processing equipment.
Technical Data
-
AWS A5.4 / SFA-5.4, E347-15
- EN ISO 3581-A, E 19 9 Nb B
- Coating Type: Basic (designed for DC polarity welding with high toughness requirements)
- Suitable for high-temperature service environments up to approximately 800 °C.
- It has a controlled ferrite content of 3-8 FN and deposits a weld with less susceptibility to embrittlement and good scaling resistance.
