Submerged arc flux designed for use with solid and tubular 400 series stainless wires. Excellent recovery of alloying elements such as Cr, Ni, Mo, Nb, and V. Excellent slag removal at high temperatures with oscillated welding technique.
Classification:
HF-N Sub-Arc Flux
Description
Welding Positions:
welding fluxes from undamaged moisture proof packaging can be used without costly re-drying. The flux recycling system must be free from moisture and oil. Slag and millscale must be removed from the recycled flux. At least one part of new flux to three parts of recycled flux must be added. From open packaging and if the flux has been exposed to moist conditions, re-drying is recommended. Agglomerated fluxes should be re-dried at a temperature of 300-350°C (570-660°F) for a minimum of 2 hours. Re-dried flux must be stored at 150±25°C (300±45°F) before use. Re-drying should be made maximum three times.
Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical depending on the type and
thickness of steel being welded.

• Agglomerated flux
• Flouride-basic type
• For submerged arc hard surfacing
• Non alloying
• For stringer or oscillated welding
• For single and multi layer applications
• Self peeling slag at high currents and temperatures up to 450⁰C (850⁰F)
