Tungsten Carbide Flux‑Cored Wire Dune NS250 is a gas‑shielded hardfacing flux‑cored wire with nickel‑based matrix and cast tungsten carbide particles. Designed for heavy abrasive wear and moderate impact conditions, it is suitable for automated/robotic hardfacing, and serves as an import‑substitute alternative to imported tungsten carbide welding consumables.

Its high‑toughness nickel‑based matrix encapsulates tungsten carbide particles, delivering superior resistance to hot cracking and spalling compared with iron‑based tungsten carbide wires. It achieves metallurgical bonding with base metals with controllable dilution rate. Tungsten carbide particles are less prone to melting and burnout, the hardfacing deposit resists chipping, and multi‑layer hardfacing is feasible.hardfacing tungsten carbide flux‑cored wire
