NT® continuous-cast rods

Gas- and TIG-welding rods

Bare, continuous-cast welding rods of corrosion- and wear-resistant Co- and Ni-based alloys are intended for weld surfacing of unalloyed, low- and high-alloy steels, tool steels, and corresponding cast steel, as well as cast-iron alloys. During recent years, the importance of Co- and Ni-based hard alloys has steadily increased in the field of weld-surfacing technology. Thus, Co-Cr-W-C alloys are now of vital importance for cladding of sealing surfaces, for instance, on valves and fittings exposed to gas, acids, and steam. Welding rods of this kind can be manufactured in any desired length.

Typical fields of application

• Engine valves and seats for automotive and naval construction,
• Valves, bushings, seat rings, spindles for power-plant construction,
• Extruder and worm conveyors as well as bushings for the plastics industry,
• Seat and guide surfaces for valves, fittings, and pumps,
• Cutting edges and knives, as well as agitators for the woodworking and paper industries,
• Transport and guide rollers, hot shears, rolls for rolling mills,
• Drill bits, drill heads, stabilisers for drilling equipment
• Die-casting moulds and forging dies, as well as extrusion dies for rubber, glass, or plastics.
