AWS A5.5: E10018-D2
Superior Crack Resistance | Low Hydrogen | Impact Toughness at -50°C
A basic coated, iron powder electrode designed for high yield strength steels requiring excellent impact toughness at sub-zero temperatures. With a diffusible hydrogen content of less than 4.0 ml/100g and smooth, ripple-free bead profile, it is ideal for heavy-duty structural welding applications in demanding environments. Wields a crack-resistant, radiographic-quality weld.
