Zetium - Analysis of stainless steel

This study demonstrates the accuracy and precision that the Metals edition of the Zetium spectrometer can deliver for controlling the composition of stainless steel, as well as the speed of analysis so important for controlling the cost of production.

Stainless steel is defined as a ferrous alloy with a minimum chromium content of 10.5 wt%. In reality there are many different types of stainless steel, which can include other alloying elements like nickel, manganese and molybdenum. The compositions of stainless steels are carefully controlled to obtain specific corrosion-resistant characteristics and crystalline structure, which in turn affect their hardness and strength. Stainless steel's resistance to corrosion and staining, low maintenance, relative inexpense, and familiar luster make it an ideal base material for a host of commercial applications, for example, household cutlery, surgical tools and many other devices.
