Positive Material Identification

Positive material identification (PMI) can also be performed at John Mayes. Our operators can identify a wide range of steels from Low Alloy Carbon, Ferritic Stainless, Ferritic-Austenitic, Austenitic, Martensitic, and Nickel Alloy steels. Typical grades are F5/P5, F9/P9, F91/P91, 316/316L, F51, F53, F55, F44, Alloy 625, Alloy 825 and Alloy C276. We test using a Niton XRF portable instrument; this gives us the ability to analyse the material and provide you with complete certification which lists all elements identified by our equipment.
