Positive Material Identification (PMI)
Rapid, non-destructive alloy verification to eliminate material mix-ups and guarantee the metallurgical integrity of critical components.
Overview
Positive Material Identification (PMI) is an advanced analytical technique used to determine the exact elemental composition and alloy grade of a metal component. In the engineering and lifting sectors, the consequences of a material mix-up can be catastrophic. Installing a component made from standard carbon steel when a high-tensile alloy or corrosion-resistant stainless steel was specified can lead to sudden structural failure under load or rapid environmental degradation. Our PMI services utilise state-of-the-art, handheld X-Ray Fluorescence (XRF) analyzers to provide instantaneous, laboratory-grade alloy verification directly on-site. This non-destructive methodology is crucial for quality assurance during the fabrication of crane structures, the validation of incoming replacement parts, and the reverse-engineering of legacy lifting equipment where original material documentation is unavailable.
The rigorous application of PMI mitigates the immense risk associated with counterfeit materials and supply chain errors. For heavy industry, offshore operations, and petrochemical plants, ensuring that the correct material grade (e.g., distinguishing between 304 and 316 stainless steel, or verifying high-strength structural alloys) is a fundamental compliance requirement. Our certified technicians rapidly screen welds, structural plates, bolts, and forged lifting accessories, comparing the elemental breakdown against extensive internal alloy libraries. By providing definitive proof of material composition, our PMI services empower procurement officers and engineering teams to confidently release equipment for service, ensuring compliance with strict WHS obligations and safeguarding the operational integrity of high-risk plant.
Compliance Standards
- API RP 578: Material Verification Program for New and Existing Alloy Piping Systems (Industry Standard)
- ASTM E1476: Standard Guide for Metals Identification, Grade Verification, and Sorting
- AS/NZS ISO 9001 requirements for traceability and material control
- WHS Regulations regarding design registration and material specification compliance

What's Included
Every engagement includes comprehensive documentation, engineering sign-off, and compliance certification issued by registered engineers.
X-Ray Fluorescence (XRF) Analysis
Deployment of advanced handheld XRF analyzers to excite surface atoms and measure the resulting fluorescent x-rays, determining elemental composition.
Instantaneous Alloy Grade Matching
Real-time comparison of the chemical breakdown against extensive on-board grade libraries to immediately identify the specific alloy (e.g., 4140, 316L, 6061).
Trace Element Analysis
Precise measurement of alloying elements such as Chromium, Nickel, Molybdenum, and Vanadium to differentiate closely related material grades.
Weld Consumable Verification
Confirmation that the correct welding filler wire or electrode was used during structural repairs to prevent galvanic corrosion and ensure joint strength.
Incoming Materials QA/QC
Rapid batch screening of incoming structural steel, fasteners, and lifting hardware to verify supplier mill certificates.
In-Situ Non-Destructive Testing
The XRF process leaves no physical mark or radiation residual on the component, allowing for 100% testing of critical in-service parts.
Comprehensive Material Certification
Provision of detailed analytical reports documenting the exact chemical composition and verified alloy grade for inclusion in the asset's engineering dossier.
