LH 98DS

High-strength alloyed basic electrode

Product description

High-strength, low-hydrogen basic electrode for joining fine-grained steels over a wide temperature range (-50 to +500°C). From non-alloyed C-Mn steels to treated low-alloy steels.

Good resistance to fatigue and corrosion in the presence of sulfur and phosphorus. Pleasant melting, easy slag detachment, good bead appearance.
