ESAB OK 48.04 L
The ESAB OK 48.04 L is a low-hydrogen, basic-coated LMA (Low Moisture Absorbing) electrode for welding mild and low-alloy steels. It provides excellent mechanical properties, making it suitable for welding in high-stress environments where cracking must be minimized. This general-purpose electrode offers stable arcs and smooth weld deposits, ensuring high-quality welds in a wide range of applications.
Classified under AWS A5.1: E7018 H4 and EN ISO 2560-A: E 42 4 B 32 H5, OK 48.04 L is highly versatile and can be used with both AC and DC+(-) currents. The low diffusible hydrogen content (< 4.0 ml/100g) reduces the risk of hydrogen-induced cracking, making it a reliable choice for critical welds.
