RATNA 7018 Spl (AWS A5.1: E7018-1)

Product Specification

Hydrogen controlled, Basic coated , Iron powder type electrode for outstanding toughness Impact properties.

 CLASSIFICATION          : AWS/SFA-5.1: E 7018-1, BS 639 E 5122RR21032
                                            IS-814: EB 5426 H3JX, DIN 1913 E 5122RR1135200

APPROVAL                     : BV, BAX, PDIL

CHARACTERISTICS     : An iron powder, hydrogen controlled electrode producing tough & ductile weld metal for welding heavy & rigid structure subjected to dynamic loading. The weld metal is of radiographic quality and displays remarkable mechanical properties like toughness resistance even at -50°C temperature.

APPLICATION               :
1) Suitable for high pressure boilers vessels.
2) Carbon steel rigid and heavy structures.
3) Steels sensitive to hydrogen embrittlement and pron to crack.
4) Industrial equipment subjected to severe impact.
5) off-shore drilling rigs and flat forms
6) Equipments require heavy impact at minus 46°C.
7) Thick plate of carbon steels.

RE-DRY CONDITION   : Re-Dry the electrode at 250°C-300°C for one hour before use.
