RATNA 8018 W (AWS A5.5 E 8018 W2)

Product Specification

Hydrogen controlled low alloy steel electrode designed for welding of weathering steels.

CLASSIFICATION          : AWS/SFA-5.5: E 8018 W2
                                            IS-1395: E 55BG 126Fe

CHARACTERISTICS     : A Hydrogen controlled basic coated electrode for welding weathering steels. Weld metal relatively high resistance to atmospheric corrosion. Very low level of diffusible hydrogen in welds. Weld metal gives radiographic quality.

APPLICATION               :
1) Suitable for welding of weathering steels like SAILCOR-A & CORTEN A & B steels &
   equivalent.
2) Medium tensil corrosion resistant structure steels and welding of high tensile steels.

RE-DRY CONDITION     : Re-Dry the electrode at 300°C for 1 hrs before use.
