Hydrogen controlled iron powder Electrode for welding Creep-Resistant
5Cr-0.5Mo steels.
CLASSIFICATION : AWS/SFA-5.5: E 8018 B6
IS-1395: E41 BB 626Fe
APPROVAL :
CHARACTERISTICS : A medium coated, hydrogen controlled, iron powder type electrode, producing 5% Cr-0.5% Mo deposit. Weld deposit is of radiographic quality, highly resist to corrosion, oxidation and exhibits creep resistance property at elevated temp. up to 550°C. The finish is excellent.
APPLICATION :
1) Ideally suitable for oil refinery.
2) Petrochemical industries, chemical industries.
3) Power house applications where steels of similar compositions are used.
RE-DRY CONDITION : Re-Dry the electrode at 250°C for 1 hrs before use.
