diffusion-alloyed steel powders

used to produce high-strength sintered P/M products
advantages:
  1. Maintenance of high inherent compressibility of the base iron
  2. Increased green strength
  3. Reduced risk of alloy segregation and dusting during transportation of the powder mix
  4. Homogeneous distribution of alloying elements
  5. Good sinterability
  6. Outstanding stability of this composite-type base powder

The diffusion-alloyed steel powders overcome the specific limitations of both premixed and prealloyed powders by combining the compressibility of a pure iron powder with the lack of segregation of a prealloyed powder. The diffusion-alloyed steel powders have been successfully used to produce high-strength sintered P/M products through single-press/single-sinter processing.

Applications of diffusion-alloyed steel powder:

  • High strength applications in sintered and sinter hardened condition
  • High strenath and wear resistance when sinter hardened
  • Parts where good dimensional control is critical
  • Gears, synchronizing and oil pump parts
