1.1 This test method covers for the atomic emission vacuum spectrometric analysis of stainless steel in solid form by the point-to-plane excitation technique for the following elements in the concentration ranges shown:
|Element||Concentration Range, %|
|Chromium||17.0 to 23.0|
|Nickel||7.5 to 13.0|
|Molybdenum||0.01 to 3.0|
|Manganese||0.01 to 2.0|
|Silicon||0.01 to 0.90|
|Copper||0.01 to 0.30|
|Carbon||0.005 to 0.25|
|Phosphorus||0.003 to 0.15|
|Sulfur||0.003 to 0.065|
1.2 This test method is designed for the routine analysis of chill-cast disks or inspection testing of stainless steel samples that have a flat surface of at least 13 mm (0.5 in.) in diameter. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials.
1.3 Analytical curves are plotted using the concentration ratio method as shown in Practice E 158
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
