Field Metallurgical Services
Positive Material Identification (PMI)
Our technicians are cross trained in instrument technology, alloy composition, metallography, nuclear theory, industrial standards and statistical analysis. When we arrive on-site you can rest assured that we are fully capable of providing your specific needs with accurate results. Put your trust in a certified laboratory.
Heat Treatment VerificationWe are capable of differentiating between varying degrees of heat treatment. We can help grade out your Precipitation Hardened alloys such as 17-4PH, 15-7MoPH and Inco 718.We can determine if your material was stress-relieved or quenched and tempered.
We can do this without destroying your parts.
Carbon Analysis/ContentAs part of our PMI services we routinely measure Carbon in all alloys
We measure carbon in L-Grade stainless in amounts as small as 0.002%.
Nickel alloys pose no problem to us.Carbon steels are also easily measured and analyzed.
Custom CalibrationOur custom calibrations allow us to perform accurate assessments of your micro-alloyed materials.
Examples would include A572-50, A500, API X65 and A709-50.When grading carbon steels accurate calibrations are critical.
Hardness TestingHardness testing is sometimes regarded in a condenscending manner.
However, when performed conscientiously, hardness testing provides several valabule insights on a material’s properties.
Equipped with UCI hardness testers with closest performance of the desktop counterparts, our technicians are trained to perform this service in a meticulously controlled fashion.This allows us to field-evaluate material to a degree previously unattainable.
We own 13 Fischer Ferritescopes which are the Cadillac of the field ferrite measuring industry.We are very experienced in measurement and evaluation of duplex materials. We have good experience regarding detection of the presence of sigma phase in duplex/super duplex materials.Our documentation reports of these examinations sets the industry standard and meets/exceeds all known Specifications.We routinely measure the Ferrite content of austenitic stainless steel welds.
Grain StructureWe perform field grain structure analysis on everything from A36 to Duplex 2507 to Inco 718.We have run preliminary procedure testing for Schlumberger on Inco 718. We have performed analysis of API X-grade piping for Duke/DCP since 1999.
We are capable of filed-duplication of almost every lab procedure performed in the petro-chemical and power generation industry.We have etched Inco 800 in the field in out of position heater configurations.We have etched Super Duplex material in a shop environment (within OSHA safety regulations).We have performed Copper Sulfate tests in shop environments and not violated OSHA regulations.
Elemental CompositionWe typically render results in weighted averages.You will not receive a simple Identification Only(ID) reports from us.There are too many possibilities of error involved in simple ID evaluations based on analyzer/screen readouts.Our technicians do not simply “parrot” screen info…
We analyze the weighted averages
We calculate/determine accuracy
We analyze the data
We report the results in a thorough, easy to understand report form
