Dune NS340 is a nickel‑based hardfacing cored wire with high‑content tungsten‑carbide hard phases.
It delivers excellent resistance to abrasive wear combined with corrosion and moderate‑temperature service, ideal for petrochemical, valve, slurry and mining components.Hardness: HRC≥55. High retention rate of WC particles, outstanding anti‑abrasion performance against sand, slurry and mineral particle erosion.
Stable arc, low spatter, smooth bead appearance, good slag removal. Suitable for semi‑auto & robotic MAG hardfacing. Good crack resistance for multi‑layer deposits, well‑controlled base‑metal dilution.
Typical applications: slurry valves, trims, pump impellers, agitators, screw conveyors, valve seats for corrosive‑abrasive service in petrochemical, mining & cement industries.
