SelectWear 63-MCO

Hardsurfacing / Metal Cored / Self Shielded

Resources

Features

  • Deposits primary chromium carbides and secondary columbium carbides in a martensitic matrix
  • Wear life is increase by 33% over standard chromium carbide alloys
  • Will retain hardness and wear resistance into the 1200-1400F range
  • Slightly improved abrasion resistance and reduced impact resistance compared to chomium carbide bearing hardfacing products
  • Maximum of 2 layers is recommended
  • Applications include: Grinding/pulverizing rolls and table segments, wear plates, clad pipe, fan and mixer blades
