1.1This test method² covers the analysis of stainless and alloy steels by wavelength dispersive X-ray Fluorescence Spectrometry for the determination of the following elements:

Element	Range, Mass Fraction %
Chromium	1 to 25
Cobalt	0.05 to 0.45
Copper	0.06 to 3.5
Manganese	0.3 to 5.5
Molybdenum	0.05 to 3.5
Nickel	0.7 to 35
Niobium	0.06 to 1.3
Phosphorus	0.01 to 0.03
Silicon	0.2 to 2
Sulfur	0.02 to 0.35
Titanium	0.013 to 0.5
Vanadium	0.04 to 0.25

Note 1-Mass fraction ranges can be extended upward by demonstration of accurate calibrations using suitable reference materials.
