Bohler-Uddeholm BÖHLER S692/S693 MICROCLEAN® PM M4 High Speed Steel
Categories: Metal; Ferrous Metal; Tool Steel

Material Notes: Description: S692/S693 MICROCLEAN are high-sulfur and low sulfur versions of high-carbon PM M4 high speed steel that is produced using state-of-the-art “Generation 3” powder processing technology. This technology provides an exceptional degree of homogeneity and refinement of the primary carbide size distribution in the HIP-consolidated and forged or rolled product compared to conventionally ingot-cast tool steels.

Applications:

    Premium Cutting Tools:
  • Milling cutters
  • Broaches and shaper cutters
  • Taps and reamers
  • Circular and dovetail form tools
      Cold Work Tooling:
    • Progressive dies
    • Fine blanking
    • Cold heading
    • Roll forming
    • Powder pressing
    • Slitter knives
    Color Code:
    S692 MICROCLEAN: Light Blue/Pink
    S693 MICROCLEAN: Black/Light Blue
