HF-50NiM – Seamless Rutile Flux Cored Wire for Mild Steel | Designed for Norway
The HF-50NiM seamless flux cored wire delivers reliable performance for mild steel and structural fabrication. It combines seamless rutile technology with excellent arc stability, producing smooth, clean welds and minimal spatter.
Therefore, it is ideal for shipbuilding, offshore platforms, pipelines, and general steel fabrication where weld integrity and efficiency are essential.
Because of its copper-coated, seamless construction, the wire eliminates moisture absorption and hydrogen pickup. As a result, it maintains extremely low hydrogen content (<3.0 ml / 100 g), which minimizes cracking and improves long-term weld performance.
In addition, it offers reliable impact toughness down to −60 °C, ensuring consistency even under cold Norwegian conditions.
Key Advantages
Excellent arc stability and easy slag removal
Very low hydrogen diffusion for enhanced weld quality
Smooth bead appearance and reduced post-weld cleanup
Reliable mechanical strength down to −60 °C
Seamless design – no re-drying required
Suitable for all welding positions
Available exclusively in Norway from RAM SVEIS OG BEMANNING AS, with ready stock in Søgne (Kristiansand)
