Chromium-nickel wire is designed welding low carbon molybdenum-bearing austenitic alloys of type 18-8.
A silicon admixture improves welding properties such as wetting, for optimal weld ease and appearance. Higher productivity can be realized using the MIG welding process.
Benefits: Excellent ignition properties, great arc stability on high currents, good wire resistance to corrosion, welding in all positions
Applications: Chemical and food industries, as well as for welding pipelines, pipes and boilers.
