Значение и использование

The chemical composition of high manganese steel alloys must be determined accurately to ensure the desired metallurgical properties. This procedure is suitable for manufacturing control and inspection testing.

Область применения

1.1 This test method provides for the analysis of high manganese steel by atomic emission spectrometry using the point-to-plane technique for the following elements in the concentration ranges shown:

ElementsConcentration Range, % Aluminum (Al)0.02 to 0.15 Carbon (C)0.3 to 1.4 Chromium (Cr)0.25 to 2.00 Manganese (Mn)8.0 to 16.2 Molybdenum (Mo)0.03 to 2.0 Nickel (Ni)0.05 to 4.0 Phosphorus (P)0.025 to 0.06 Silicon (Si)0.25 to 1.5

Note 1—The ranges represent the actual levels at which this method was tested. These concentration ranges can be extended to higher concentrations by the use of suitable reference materials. Sulfur is not included because differences in results between laboratories exceeded acceptable limits at all analyte levels.

1.2 This test method may involve hazardous materials, operations, and equipment. 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.
