PM M4 Tool Steel
Properties
PM M-4 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
Typical Uses
Typical applications include: 
  • Form Tools
  • Blades
  • Broaches
  • Chasers
  • Die Inserts
  • Punches
  • Reamers
  • Slitter Knives
  • Taps

PM M4 Tool Steel

PM M4 is a Molybdenum-Tungsten tool steel with high Carbon and Vanadium for excellent wear resistance. This high-performing tool steel is made via the Powder Metallurgy process, which creates a highly refined microstructure noted for its uniform distribution of carbides.  The fine grain size and superior cleanliness result in a high-speed flexible tool steel that provides a unique combination of high wear-resistance with high impact toughness and bend strength. It is ideally suited for heavy-duty cold-work applications.  PM M4 offers improved cutting tool life compared to conventionally-wrought M1, M2, M7, and other lower-alloyed high-speed steels. It excels in cold work tooling applications, outlasting high-carbon, high-chromium die steels such as D2 and D3.

Alro stocks in Rounds ½”-12” diameter and Plate cut to size ½- 3” thick.  Material is provided decarb-free and oversized to finish at the nominal dimensions.
