Laboratory Inspection

Spectrum Thermal Processing has a full-service metallography lab in-house to compliment our heat treating processes. 

  • Rockwell, Rockwell Superficial and microhardness
  • Case hardness profile analysis
  • Metallurgical evaluation and microstructure analysis
  • Surface contamination testing
  • Fracture grain size testing

Have small parts or geometry that do not lend themselves to macrohardness testing? Microhardness mounting can be used to stabilize the parts and make testing easy.

Mounting isn't limited to microhardness testing, here we used it to allow for macrohardness testing on spherical parts.
