GRICON GREEN(SPL) H4R VACUUM PACKED

IDENTIFICATION : GRICON GREEN (Spl) E-7018-1 H4R

CLASSIFICATION : AWS/SFA5.1: E 7018-1H4R IS814: EB5626H3 JX, BS: E5155B(11026H), DIN : 5155B1029

DESCRIPTION :

Vacuum packed heavy coated basic type, hydrogen-controlled, iron powder electrode with high deposition efficiency. The electrode deposits weld metal which is of radiographic quality and meets impact requirements at minus 46° C. The weld deposit is tough, ductile and is highly resistant to hot or cold cracking even when subjected to high stresses, dynamic loading etc.

TYPICAL APPLICATION :

For the welding of structural steel where resistance to brittle fracture is required under adverse operating conditions such as those found in off-shore production platforms. Used for production of pressure vessels, bridges, pipelines Recommended for higher carbon & higher Sulphur steels, which are susceptible to hydrogen induced cracking. For welding SAILMA 350HI steel. For shipbuilding and ship repair application.


DIFFUSIBLE HYDROGEN : Max 4.0ml/100g of weld metal

ASME IX Qualification : QW- 432 F-NO 4, QW- 442 A-NO 1
