What Is Positive Material Identification (PMI)?

Positive Material Identification, commonly known as PMI, is a testing process used to identify and verify the composition of metals and alloys.


Steel City NDT uses portable X-ray fluorescence (XRF) equipment to analyze materials. During testing, the equipment detects and measures the characteristic energy levels produced by elements within the material. This information allows technicians to identify the alloys present.


Testing does not damage the material, and results are available immediately after the inspection is completed. This makes PMI a valuable option when material verification is needed without affecting the component being tested.

Why Positive Material Identification Matters

Professional PMI testing can help Pittsburgh-area organizations:Verify material characteristics

  • Identify and verify ferrous alloys
  • Identify and verify nonferrous alloys
  • Confirm incoming materials
  • Verify materials already in stock
  • Support in-service material inspections
  • Validate components
  • Support failure analysis
  • Reduce concerns associated with material mix-ups

Material mix-ups can create significant concerns in industrial applications. Obtaining accurate information about alloy composition helps businesses verify materials before or during manufacturing, installation, maintenance, and inspection activities.


Portable XRF Testing for Material Verification

Steel City NDT uses portable XRF equipment to perform Positive Material Identification testing. Because the equipment is portable, PMI can be performed at our facility or on-site at a client's premises.
