INTERNATIONAL CLASSIFICATION

None

FEATURES & APPLICATIONS

For repair and reclamation of tools and dies subject to heat checking.

  • Tungsten free hot work tool steel electrode.
  • Deposits maintain a very sharp edge.
  • Alloying elements include molybdenum and vanadium.
  • Weld metal maintains many of the properties of H13 tool steel.
  • Also available in TIG form as product code 6111.
