Positive Material Identification (PMI) Testing in Chennai

Prevent Material Mix-Ups: PMI (XRF/OES) Testing in Chennai – Kiyo R&D LAB

Introduction

In manufacturing and fabrication, one wrong material can ruin performance, trigger audit failures, and create safety risks. That’s why positive material identification services in Chennai – Kiyo R&D LAB exist: to verify material grade with evidence, not assumptions.

What is Positive Material Identification (PMI)?

Positive Material Identification (PMI) is a non-destructive testing method used to confirm the chemical composition of metals and alloys. It verifies whether a material truly matches its specified grade—such as stainless steel, carbon steel, alloy steel, aluminum, copper alloys, and nickel alloys.

Simply put, PMI answers one question: Is this material exactly what it claims to be?

Why PMI Testing Matters

Many failures don’t happen because of poor design—they happen because the wrong alloy was used or materials got mixed. PMI helps prevent costly and dangerous issues like:

  • Wrong alloy substitution and mix-ups
  • Supplier mismatch or incorrect certification
  • Corrosion failures due to wrong grade selection
  • Heat resistance failure in high-temperature applications
  • Audit rejection and compliance risk

PMI Methods Used at Kiyo R&D LAB

1) XRF (X-Ray Fluorescence)

  • Fast, non-destructive grade verification
  • Ideal for stainless steels, nickel alloys, aluminum alloys
  • Suitable for on-site PMI and lab testing

2) OES (Optical Emission Spectroscopy)

  • Higher accuracy elemental analysis for critical applications
  • Detects light elements (e.g., carbon) where needed
  • Preferred for carbon steels and low-alloy steels

The test method is selected based on your material, standard, and application requirements.

FAQ

What is PMI testing used for?

PMI testing is used to verify the chemical composition of a metal/alloy and confirm whether it matches the specified grade.

Which method is better: XRF or OES?

XRF is fast and ideal for many alloys. OES is preferred when higher accuracy is needed and for certain elements (like carbon) in steels.

Can PMI be done on-site in Chennai?

Yes. Kiyo R&D LAB provides on-site PMI for installed parts, pipelines, structures, and fabrication yards.

What materials can be identified using PMI?

Common materials include stainless steels (304/316), carbon steels, alloy steels, aluminum alloys, copper alloys, and nickel alloys.

How fast will I get the PMI report?

Turnaround depends on sample volume and method, but PMI is generally fast and suited for urgent verification needs.
