ESAB EB 146 electrodo básico 4,0 mm x 450 mm paquete de 6 kg E7018 bajo hidrógeno

Delivers exceptional impact toughness down to -40°C with >47 J Charpy V-notch energy, ensuring integrity in low-temperature environments. This 4.0 mm basic low-hydrogen electrode from ESAB is engineered for high-strength and critical steel fabrication, offering a stable, low-spatter arc and self-releasing slag for efficient, clean welding.

Overview

The ESAB EB 146 is a basic, low-hydrogen electrode classified as AWS A5.1 E7018 and EN ISO 2560-A E 42 4 B 42 H5. Its controlled hydrogen content (H5) minimizes the risk of cold cracking, while the self-releasing slag simplifies post-weld cleanup. This electrode is suitable for welding unalloyed and low-alloy steels in all positions except vertical down.

What stands out

• High impact strength: >47 J at -40°C ensures integrity in low-temperature environments.
• Low hydrogen content (<5 ml/100g) reduces susceptibility to hydrogen-induced cracking.
• Self-releasing slag and stable arc promote efficient, clean welding.
• Versatile applications: ideal for high-strength steels, pressure vessels, shipbuilding, and structural steel.
