HIP composite technology of Kobe Steel

Kobe Steel has comprehensive HIP technology consisting of HIP equipment, Development and production of HIP lining materials, and Matching of HIP materials. This composite technology is applied to the development of HIP barrels and screws made of HYPERKTX Super Alloy.

  • Power materials for linings are compressed, sintered and strongly bonded to the base metal of the barrel by HIP (Hot Isostatic Pressing) process.
  • Barrels and screws manufactured by the HIP process have excellent wear and corrosion resistance, toughness and peel resistance.
