Hydrogen controlled iron powder Electrode for welding Creep-Resistant with High alloyed, 9Cr-1Mo steels.
CLASSIFICATION : AWS/SFA-5.5: E 9016 B9
CHARACTERISTICS :
A basic coated, hydrogen controlled, iron powder type electrode, producing 9% Cr / 1.0% Mo deposit. Weld deposit is of radiographic quality, highly resist to corrosion, oxidation and exhibits creep resistance property at elevated temp. up to 600°C. The finish is excellent.
APPLICATION :
- Ideally suitable for oil refinery petrochemical industries, chemical industries.
- Power house applications where steels of similar compositions are used.
- For welding 7-10% Cr 1% Mo steels and castings of similar compositions.
RE-DRY CONDITION : Re-Dry the electrode at 350°C for 1 hrs before use.
