Positive Material Identification (PMI)

Are you looking for Independent Positive Material Identification?

In today’s industrial world, many exotic materials are being used to engineer and design products with a purpose to achieve the safest and longest life expectancy for the components used. Positive Material Identification (PMI) technology allows us to establish the chemical composition of many of these metallic alloys. Using X-ray fluorescence (XRF) for PMI, this equipment is safe, handheld and portable.

Because the output report lists the quantities of the alloy’s constituent elements by percentage, PMI offers an alternative to the review of mill certifications and acceptance of materials through paperwork alone. Mill certification is generally limited to a sample that represents the entire heat; however, XRF can identify the material composition on specific pieces and at specific locations on the piece.

KTA's Positive Material Identification Offers the following:

  • Material Traceability of Bolts & Fasteners
  • Verification of Alloy Rebar & Strands
  • Verification of Weld Wire Composition
  • Verification of Pipeline Material
  • Verification of Chemical Composition Via NDT Methods
  • Immediate results
  • Excellent accuracy

KTA Positive Material Identification Known Metal and Alloys:

  • Aluminum alloys
  • Chromium-Molybdenum steels
  • Cobalt alloys
  • Copper alloys
  • Exotic alloys

Why Use KTA for Positive Material Identification?

The use of combining dissimilar materials and products of different chemical compositions is more common now than in the past. Whether alloying for strength, longevity or durability, the need for material traceability and verification is more important than ever.

KTA offers PMI services, by use of a hand-held analyzer. We are focusing on industries that we believe may benefit from this technical support by helping them meet their client and regulatory requirements–at a great value.

We are mobile, and can come to your location, eliminating the need to cut a sample and send it to us.

It typically takes about 10 seconds per reading. Depending on the proximity of locations and pieces, we may obtain over 200 readings per hour.

KTA’s Positive Material Identification Will Help Answer the Following:

  • Are these bolts stainless steel and of which alloy?
  • Is this material aluminum or magnesium?
  • Was this shaft hard-faced with the right weld wire?
  • Is there a zinc coating on this sheet metal?
  • This valve supplied to me had no material certifications. Did I get what I ordered?
