Classification:
AWS/SFA-5.1: E 7018 , BS 639 E5144B12024(H)
IS-814: EB 5426 H3JX, DIN 1913 E 5144B1026
Approval:
BIS, CIB, IRS, DNV, LLOYARDS, BV, BAX, PDIL, TOYO, BHEL, RDSO (A4)
Characteristics:
A heavy coated, hydrogen controlled, basic coated, iron powder type electrode specially designed for restrained joints subjected to dynamic loading and to achieve minimum 110% metal recovery. It possesses excellent mechanical properties, and weld deposits are highly ductile, crack resistant, and of radiographic quality.
Application:
- Blast furnace, offshore drilling rigs, and platforms.
- Penstocks and heavy structures subjected to dynamic loading and impact.
- Rail wagons and coaches.
- Industrial & mining machinery, bridges, boiler fabrication.
- Steels subjected to service at -30°C down to sub-zero temperature.
- Machinery for earth moving and road equipment.
- Atomic reactor shell and pipe work.
- Frigates & submarines.
Re-Dry Condition:
Re-dry the electrode at 250–300°C for one hour before use.
