Capabilities

Metallurgical Testing

We employ two staff metallurgists, responsible for managing our Quality program, writing proprietary heat treat and forging procedures and performing laboratory testing. Our in-house metallurgical laboratory gives us the ability to perform:

  • Hardness
    • Rockwell (B & C)
  • Tensile (axial, full size tension testing, wedge, yield)
  • Proof Loads (Internally and Externally Threaded Fasteners)
  • Impact Testing
    • Charpy V-notch
  • Plating Thickness
  • Metallographic Evaluation
    • Macroetch
    • Decarburization
    • Grain Size
    • Banding Evaluation
    • Phase Evaluation
    • Grain Flow
  • Quantitative Chemical Analysis
    • Optical Emission Spectroscopy
      • Capable of testing alloy steels, stainless steels and Nickel based alloys

We utilize a full complement of inspection equipment, including coordinate measuring machine, GAGEMAKER, ring and plug gages, tri-roll gages and optical comparator. We can offer ANSI System 21, 22 and 23 thread gaging.
