What's that material?: Using XRF technology to identify alloysMany alloys—stainless steels, HASTELLOY®, INCONEL®, INCOLOY®, MONEL®, duplex and superduplex alloys—are similar in appearance and easily mixed up after mill test reports (MTRs) and heat stamps are removed in material processing. These mix-ups can have serious consequences to the end user, including product rework, factory downtime, or premature product failure. A single mistake may cost hundreds of thousands of dollars in materials and labor to correct. In addition, any loss of consumer confidence resulting from shipping incorrect material carries incalculable costs.
