Hard Facing ALLOY-CN

Hard Facing ALLOY-CN

Flux core wire for self shielded metal open arc welding
Products Inquiry

Description

1. Features
  • High chromium cast iron series is used for hard faced components, and metal cored flux cored welding wires are severely worn and medium impacted by the machine.
  • Hardfacing materials that effectively prevent soil, sand or other abrasive grinding.
  • Niobium carbide and chromium carbide carbide have good wear resistance to high hardness fine abrasive particles.

2. Applications
  • Overlay welding of roller press pattern layer and vertical mill hard surface layer.
  • Material conveying equipment and metallurgical conveying equipment in steel industry, such as ladle and tooth surfacing strengthening.
  • Dredger bucket, towing bucket, coke hammer.
  • Pump impeller, fan blade, stone roller, wear plate.
