Applied Technical Services provides onsite PMI services that support our clients’ quality control and safety efforts.
What is Positive Material Identification?
Positive Material Identification (PMI) is the process of verifying a metal alloy’s chemical composition to ensure it meets required specifications. Using non- or minimally‑destructive testing technologies, PMI measures key alloying elements, including, but not limited to:
- Nickel
- Chromium
- Molybdenum
- Vanadium
PMI ensures that an alloy or metal’s chemical composition aligns with required standards and specifications, helping verify a material’s suitability for its intended application. This process is essential for ensuring the mechanical integrity of materials and determining their ability to withstand mechanical stress. PMI is commonly used in the following industries:
- Aerospace
- Oil and gas
- Power generation
Our Onsite PMI Services and Analytical Capabilities
Our laboratory provides accurate, rapid, and convenient onsite PMI services, helping clients evaluate their materials from their own sites and facilities. Our experts use state-of-the-art portable X‑ray fluorescence (XRF) and optical emission spectroscopy (OES) instruments to determine a material’s alloy grade and chemical composition. These techniques allow us to analyze a wide array of metal alloys, including specialty metals. Our team delivers immediate, decision‑ready results supported by clear documentation and expert interpretation. Our services help our clients do the following:
- Ensure components comply with ASTM, ASME, and API standards
- Confirm a material’s composition
- Verify the filler material of welded components
- Avoid misidentifying materials
- Conduct failure analysis
- Reduce the likelihood of a material’s mechanical failure
Why PMI Matters Across Industries
PMI is an important safeguard for industries that rely on the performance and durability of metallic components. In many industries, including power generation, oil and gas, and aerospace, minor deviations in alloy chemistry can compromise materials, leading to corrosion, cracking, or mechanical failure. PMI can help businesses meet safety requirements and reduce the risk of costly repairs, unplanned outages, and safety incidents. It also supports long‑term asset integrity programs by providing traceable evidence of material compliance during installation, maintenance, and repair. PMI strengthens quality assurance efforts and helps organizations maintain operational confidence by confirming that the right materials are used in the right applications.
