Bohler Fox EV 50 (Basic Low Hydrogen) Mild Steel Electrodes
Basic coated electrode engineered for high-quality welds. Excellent strength and toughness properties down to -50C. Metal recovery approximately 110%. Good weldability in all position except for vertical-down. Very low hydrogen content (acc. AWS condition HD < 4 ml/100g weld metal) with a moisture resistant coating. Suitable for welding steels with low purity and high carbon content. Welding in steel construction, boiler and tank manufacture, vehicle construction, shipbuilding, and machine construction as well as for buffer layers on build ups on high carbon steels. Especially suitable for off-shore construction, CTOD tested at -10 C. BÖHLER FOX EV 50 can be used in sour gas applications
Features
- Offers exceptional resistance to cold cracking in high-restraint joints.
- Diffusible hydrogen content stays strictly below 4 ml/100g (H4R rating).
- Specialised basic coating formulation strongly resists atmospheric moisture pickup.
- Maintains reliable impact energy strength down to temperatures of -50°C.
- Delivers a highly concentrated, predictable directional arc.
- Minimal weld spatter reduces clean-up and grinding time.
- Slag lifts away cleanly, reducing the risk of slag inclusions.
- Produces clean weld metal with excellent X-ray soundness.
- Exceptional control when laying root runs and filling gaps.
