High Speed Steels

High Speed steels are highly alloyed steels designed to cut other materials efficiently at high speeds while withstanding the extreme heat generated at the tools cutting edge.

  • These steels are heat treated and used at high hardnesses typically 62 HRc and above.
  • They maintain high hardness at elevated temperatures while having enough impact toughness to handle interrupted cut tooling applications.

High Speed Steels are highly alloyed and contain the following elements:

  • Tungsten (W)
  • Molybdenum (Mo)
  • Vanadium (V)
  • Chromium (Cr)
  • Cobalt (Co)

The most important properties for High Speed Steels are:

  • Toughness
  • Red Hardness
  • Wear Resistance

Methods for production:

  • Conventional
  • Powder Metallurgy (PM)
  • Spray Formed

Available in the following sizes:

  • Rounds: 0.500" dia. through 6.000" dia.

M50

M50 is a general purpose high speed steel with a good balance of toughness, wear resistance, and red hardness.
M50 is used for metal cutting, wood and plastics cutting and cold work tooling.

Inquire for available sizes.

PM32CO

PM32CO is a Particle Metallurgy Super High Speed steel with excellent hot hardness along with good wear resistance and toughness.

Available in the following sizes:

  • Rounds: 0.765" dia. through 7.75" dia.

PSB M2

PSB M2 is a premium spray formed M2 High Speed Steel. It is ideal for many high speed applications providing improved toughness and higher wear resistance than conventional M2. The spray forming process imparts a more homogeneous structure with improved carbide distribution and a preferred spherical carbide shape.
