Pmi Alloy Steel Analysis using XRF 

Pmi steel is one of the most widely used material in large structures. As its name suggests the main alloying constituent is carbon. XRF comes in handy when there’s a need to quickly sort carbon steel from other alloys like in scrap metal industry or during incoming inspection. Alloy steel properties are determined not by carbon. XRF is indispensable for the analysis of this type of steels, because contents of alloyants such as Mn, Ni, Mo, V etc, which determine steel properties
and cost, are measured within seconds.
