Positive Material Identification (PMI)
Verification that materials meet specified compositions and alloy standards.
Positive Material Identification (PMI) ensures that materials meet specified compositions and standards. By analyzing the elemental makeup of metals and alloys using XRF, OES, or LIBS, this method prevents costly errors and ensures the integrity of components in critical applications.
PMI is a critical control for carbon-versus-stainless mix-ups, low-temperature service verification, and alloy verification during turnaround fabrication.
