Metallographic Characterization of the Microstructure of Tool Steel

Five Five-Step Method for Preparing Tool Steel

  1. 120-to 240-grit SiC, water cooled, 240-300 rpm, 6 Lbs/specimen, UP
  2. 9-μm diamond on UltraPolsilk cloth, 150 rpm, 6 Lbs/specimen, 5 min
  3. 3-μm diamond on TriDentcloth, 150 rpm, 6 Lbs/specimen, 4 min
  4. 1-μm diamond on TriDentcloth, 150 rpm, 6 Lbs/specimen, 3 min
  5. 0.05-μm MasterPrepAlumina suspension on MicroCloth, 120-150 rpm, 6 Lbs/specimen, 1-3 min

Use contra rotation (head rotates in opposite direction to platen if the head speed is <100 rpm.

Step 4 is optional; use with more difficult to prepare specimens.
