RATNA 8018 C1 (AWS A5.5 E8018 C1)

Product Specification

A Basic coated 2.50% Ni alloyed electrode for welding low ally steels.

CLASSIFICATION          : AWS/SFA-5.5: E 8018 C1
                                            IS-1395: E 55BC 126Fe

CHARACTERISTICS       : A medium coated Hydrogen controlled, basic coated iron powder type electrode presence of Mn & Ni in appropriate proportion imparts to weld a high degree of low temperature notch toughness. The weld deposit controlled 2.50% Ni which imparts good resistance to brittle fracture down to -59°C.

APPLICATION               :
1) Suitable for fabrication of LNG storage tanks.
2) Liquified gases, cryogenic vessels, to weld 2.25% Ni steels, oil refinery valves, pressure   
   vessels.
3) Construction of components to be subjected to low temperature service in petrochemical industries.

RE-DRY CONDITION     : Re-Dry the electrode at 300°C for 1 hrs, for best results..
