Elétrodo básico ESAB EB 150 3,2 mm 6 kg E7018-1 H4R

The ESAB EB 150 is a high-quality basic, low-hydrogen electrode designed for welding unalloyed and low-alloyed high-strength steels. With an AWS classification of E7018-1 H4R and EN ISO classification of E 42 4 B 42 H5, this electrode delivers excellent mechanical properties and low hydrogen content (<5 ml/100g), making it ideal for critical applications such as pressure vessels, shipbuilding, structural steel, and pipe welding.

Advantages

Low hydrogen content ensures reduced risk of hydrogen-induced cracking. Excellent impact strength at low temperatures (100-180 J at -40°C). Smooth arc stability and easy slag removal. Suitable for all welding positions except vertical down.

Suitable for

• Pressure vessels and boilers
• Shipbuilding and offshore structures
• Structural steel construction
• Pipe welding
• General fabrication of high-strength steels
