Positive Metal Identification

The PMI division at TCR Advanced Services has an expert engineering and inspection workforce to undertake incoming material inspection and can provide on-site alloy verification for quality control and stock control purposes. TCR can analyze both melt and weld for comprehensive maintenance assessment.

TCR provides PMI services to a number of metal producers, foundries, metal fabricators, scrap yards, scrap traders in the industry, electric utility companies, fossil, nuclear power plants, refining petrochemical industry, construction engineering, and the chemical process industry.

The range of equipment available at TCR for undertaking Positive Material Identification (PMI) is unparalleled in India. TCR’s on-site inspection and testing teams have over 12 highly sophisticated Portable Alloy Analyzer Spectrometers which can in-situ non-destructively and accurately measure the chemical composition of materials. Using these spectrometers, TCR’s engineers can provide elemental identification and quantitative determination regardless of form, size, and shape. No samples need to be cut for PMI. TCR can also deploy the portable optical emission spectrometer that can detect C, S, P, Mn, and Si. Elements that can be identified using PMI include Ti, V, Cr, Mn, Co, Fe, Cu, Zn, Ni, Se, Nb, and Mo.

The team also conducts positive material identification test to detect carbon composition on-site using the ARC Met 8000, a portable optical emission spectrometer. The portable optical emission analyzer is designed to identify all the key elements in metals, especially where highest accuracy, analysis of light elements (like C, Al, S, P, Mg, Si) or sorting of low alloys and aluminum is needed. For example, it is ideal for separation of 316 H (>0.04% C) and 316 L (<0.03% C).

Using portable XRF analyzers, TCR offers scrap traders in India all the necessary data needed to take fast, informed decisions about material purchases along with the input and speed required to sort large quantities of materials, and hence utilize sales opportunities efficiently. Inspection services team of TCR supports the recycle and resell scrap traders in enhancing their profit margins by measuring precious metals in electronics - Pt, Ir, Ru, Rh, Pd. TCR also supports a scrap trader to perform scrap classification service efficiently. From titanium alloys, stainless steel, nickel superalloys, red metals to exotics, TCR can quickly provide fast, reliable results that the industry demands.


TCR’s Positive Material Identification service is fast becoming an integral part of the safety management process

TCR has provided PMI services for over 700 projects for major oil, petroleum refining, petrochemical, and electric power generation industries in India, Hong Kong, China, Singapore, Malaysia, Indonesia, Russia, Dubai, Kuwait, Kingdom of Saudi Arabia and other parts of Middle East. In addition, it has also served North America and major parts of Europe. Some PMI projects were undertaken in conjunction with the third-party inspection of EIL, Lloyds, KTI, TUV, DNV & BARC.

A wide range of alloys can be analyzed on site using PMI including:

  • Carbon and Low Alloy Steels
  • Copper Alloys
  • Stainless and High Alloy Steels
  • Aluminum Alloys
  • Nickel Alloys
  • Austenitics Duplex and Super
