A 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. The weld deposit is tough, ductile and is highly resistant to hot or cold cracking even when subjected to high stresses, dynamic loading etc.
WELD METAL ANALYSIS (RANGE) %
MECHANICAL PROPERTIES (RANGE)
• 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.
