Powder Metallurgy

Wear- and temperature resistant components made of powdermetallurgical steels, Co-based alloys, super alloys and composite materials.


Compared with the conventional manufacture of materials based on the melting technology, the Powder Metallurgy provides special advantages:

  • Alloys that cannot or can only be produced with enormous difficulties (for example higher carbide content)   
  • homogeneous material with no gravity segregation, solidification segregation, phase segregation and with isotropic properties
  • greater freedom of design of the components



Industy sector and Products


Steel production and Steel processingRoll rings, guide rollers, cooling bed rollers
Food industryKnives and cutters
Plastic industryTools for extrusion and injection molding
Automotiveand much more

Large selection of materials as well as material combinations, single part production and small series.



  • Use of gas-atomized powder in near-net shaped metal moulds

  • Hot Isostatic Pressing of the moulds at 1100°C – 1200°C and >1000 bar Bonding of the powders particles by means of the solid body diffusion
  • Mechanical removal of the moulds and further processing


Tables of the different grades [content in wt-%] – some examples

PM-Steels-Alloys (Saramet, SAM)





  • High performance cold and hot working high speed steels (Forming-, cutting and pressing tools)

  • Corrosion resistant tools; protection against intercrystalline corrosion

PM-Superalloys (Saratherm, SAT)





Typical applications for high temperature resistant PM-Superalloys are

  • high performance engine parts
  • high temperature resistant machine parts of the chemical and petrochemical industry
  • hot working tools in the diamond grinding disk- and glas industry, etc.

PM-Co-based alloys (Sarastel, SAS)





  • mining tools, cutting tools

  • corrosion resisting high temperature engineering parts
  • hot working tools




Tailored material properties in tool areas where these are required most:


  • Hardmetal (cemented carbide) – Steel
  • o-based alloy (SAS) – Steel
  • Superalloy - Steel


Advantages / Service
