High Speed Steel Powder

High Speed Steel Powder

This is a powder for producing materials for rolls, dies, cutting tool parts by HIP. This has a feature to provide fine structure.

Outline

Features

  • Gas atomization method has made it possible to produce spherical powder with high filling density and less oxygen content.
  • The combination with HIP (Hot Isostatic Pressing) has made it possible to produce materials with homogeneous microstructure when materials on which hot working could not performed before or when it is difficult to produce materials by Melting Method because segregation is likely to occur.

Main Applications

  • Various rolls (Hot rolling and Cold rolling)
  • Various tools
    (End Mill, Pinion cutter, Broach drill, Tap, Tooth-Cutting Hob, and various cutting tools)
  • Die materials and die parts (Various press dies, Punch and Pin)
  • Sintered parts
