Material Testing & Verification

A product is only as good as the materials from which it is made. The pressure to cut costs and the growth of global manufacturing have magnified the need for more accurate materials testing. BAY Technical has the equipment and qualified personnel needed for positive materials identification, alloy verification, pipe inspection, lead-based paint inspection and hardness testing. We conduct XRF Analysis, and OES spark testing to verify materials and ensure an added level of quality.

Positive Material Identification (PMI) Testing

  • X-ray Fluorescent (XRF) analyzer for alloy verification (Smart Beam feature to accurately separate alloys containing low concentrations of Titanium and Vanadium)
  • Optical Emission Spectrometer (OES) spark testing for carbon content (i.e. H and L grade stainless steels)
  • UV testing for phosphorous and sulfur content

Hardness Testing

  • Krautkramer MIC-10DL


Case Study: On-site Verification

A major US oil refiner needed to perform on-site Positive Material Identification (PMI) of field welds during a major expansion of one of their refineries. The testing required carbon content verification of 316L field welds during the fabrication of the Wet-Gas Scrubber unit. The refinery expected this testing to take six to eight weeks.


The company called BAY Technical Associates to do the testing. As a result of the extensive experience and training of our PMI technician, the testing was completed and verified in two, one-week trips. This short timeframe far exceeded the client's expectations and dramatically reduced their costs.

Case Study: Supplier Verification

A major engineering company has a continuing need to perform Positive Material Identification (PMI) of materials received in their facility prior to those materials being shipped to their vendor for fabrication.


The company uses BAY Technical Associates on a regular basis for testing consistency and proficiency. In one of these tests, prior to the machining process, a casting was found to be made from an incorrect grade of stainless steel material. Our client was able to order another casting, have it tested and shipped to their fabrication vendor in a timely manner. As a result of the PMI testing prior to fabrication, our client has lowered their overall costs, improved their quality and decreased fabrication time for their customers.

Case Study: Fabricator Verification

A major engineering and fabrication company needed to perform Positive Material Identification (PMI) during the fabrication of a large reactor for an overseas chemical company. The job would require multiple visits and multiple analyses.


The company hired BAY Technical because of our ability to quickly mobilize and our expertise in carbon level verification. Multiple visits by BAY Technical Associates were required during the fabrication process. We conducted PMI tests, including spark tests for carbon content through out the project meeting our client's and the end user's expectations and requirements.

Case Study: Fabricator Verification - Hardness Testing

A piping fabricator needed to perform Material Hardness testing of carbon steel piping after fabrication. In order for the fabricator to maintain the dimensional requirements of the project, several welds needed to be made in very close proximity. The client's construction standards have a maximum allowable hardness range that must be met for the carbon steel piping.


BAY Technical Associates was hired to perform the material hardness tests of the welds and the heat-affected zones, to ensure that the maximum steel hardness was within acceptable limits.
