More Information
Summary:A high hardness and wear-resisting flux cored wire, wherein said core includes (in wt.%): molybdenum 1-10; tungsten 1-10; graphite 1-10; nickel 1-7; vanadium 2-10; chromium 20-40; sodium silicon fluoride (Na2SiF6) 5-15; niobite 1-10; boron 10-15; quartz 2-10; rare earth 1-8. These components are ground into powder and stirred thoroughly and then placed onto a steel strip with a thickness of 0.25-0.6 mm. The steel strip is extruded by an extrusion press into a wire which is finally drawn out by a wire drawing machine, and the high hardness and wear-resisting flux cored wire is thus obtained. The wire can be used for repairing welding cold roll with a hardness of HRC 62-65 without cracks.
