Hydrogen controlled iron powder Electrode for welding Creep-Resistant 9Cr-1Mo steels.
CLASSIFICATION : AWS/SFA5.5: E 8018 B8
IS-1395:E41 BB 826Fe
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 :
1) Ideally suitable for oil refinery petrochemical industries, chemical industries.
2) Power house applications where steels of similar compositions are used.
3) For welding 7-10% Cr 1% Mo steels and castings of similar compositions.
RE-DRY CONDITION : Re-Dry the electrode at 250°C for 1 hrs before use.
