Positive Material Identification

Positive Material Identification (PMI) is the analysis and identification of metallic alloys through Nondestructive Testing (NDT) methods for quality control and safety compliance. PMI testing provides a cost effective method of identifying material alloy, grade, and composition, prior to fabrication, or retroactively.

At Quality Testing Services, Inc., we understand that mishaps happen. It’s not uncommon to inadvertently mix-up materials, stamp the wrong grade, or lose the paperwork at any stage in the process. That’s why we offer Positive Material Identification services as a rapid, nondestructive method to accurately identify questionable metal alloys or grades. Once Quality Testing Services positively identifies the alloy, you can be confident the material will meet your specifications.

To minimize potential risk, it’s important to verify every alloy and component during each stage of fabrication or installation. Likewise, it may be necessary to perform positive material identification retroactively on existing components, piping, or other in-process systems. Our Positive Material Identification service is a key element in providing a safer work environment, assurance projects are completed on time, and avoidance of critical, costly mistakes.

Quality Testing Services’ certified PMI technicians can analyze, and identify the alloy, grade and composition of metallic materials quickly, and provide on the spot results without negatively effecting the integrity of the material. Our state of the art, X-Ray Fluorescence (XRF) PMI Analyzer can identify materials whether in the field or on the shop floor, with lab-quality results, including; a Certificate of Analysis, and optional detailed Analysis Report based upon your requirements.

Our advanced XRF, PMI Analyzer incorporates a unique library of over 400 alloy grades, designed to provide superior accuracy in grade identification of alloy chemistry for up to 30 of the most common elements in tens of thousands of alloy grades. Categories of alloys that can be accurately identified and analyzed include:

  • Stainless steels
  • Cr-Mo steels including V stabilized versions
  • Low alloy steel
  • Tool steels
  • Nickel alloys
  • Copper alloys
  • Titanium alloys
  • Aluminum alloys
  • Exotics, such as Zirconium and Tantalum alloys

Quality Testing Services can perform fast, accurate elemental analysis and positive material identification designed to ensure the integrity of your systems across your plant, including:

  • Raw material stock
  • Rods
  • Finished welds and weld beads
  • Bolts, rivets, and other fasteners
  • Valves and flanges
  • Tanks and vessels

With Quality Testing Services Positive Material Identification service, you can be assured of:

  • Reliable element analysis for accurate alloy and grade identification
  • Accurate material identification and alloy analysis
  • Accepted material specification requirements
  • Improved product quality and consistency
  • Validation of the correct filler material on welded components
