Dur R (Ni) is an extruded oxy-acetylene rod, a newly designed hard-surfacing product consisting of spherical cast tungsten carbide and a Ni-based alloy. Crushed cast carbide will guaranty a long life. Furthermore the Ni-based alloy provides an excellent corrosion resistance Dur R (Ni) has excellent flow and wetting characteristics at low working temperature of around 1050 °C and the deposition rate is 20-30% higher than with comparable tube metal. It is easy to use and inexperienced welders will have no difficulties to produce smooth deposits without cracks. Multi-layer deposits are possible and worn parts can be rebuild without removing the old material. The surface should be free from fats, oil, rust and other foreign matters. Use a larger tip than is generally recommended for same diameter mild steel. Use slight excess acetylene feather. The deposit is not mashinable or forgeable. Only grinding with diamond tools is possible.Dur R (Ni) is available as a 500 mm flexible rod or endless on coils.
