Значение и использование

The chemical composition of cast iron alloys shall be determined accurately in order to insure the desired metallurgical properties. This procedure is suitable for manufacturing control and inspection testing.

Область применения

1.1 This test method covers the optical emission spectrometric analysis of cast iron by use of the point-to-plane technique for the following elements in the concentration ranges shown (Note 1):

Concentration Ranges, %
ElementsApplicable Range, % Quantitative Range, %A
Carbon1.9 to 3.81.90 to 3.8
Chromium0 to 2.0 0.025 to 2.0
Copper0 to 0.750.015 to 0.75
Manganese0 to 1.8 0.03 to 1.8
Molybdenum0 to 1.2 0.01 to 1.2
Nickel0 to 2.0 0.02 to 2.0
Phosphorus0 to 0.4 0.005 to 0.4
Silicon0 to 2.5 0.15 to 2.5
Sulfur0 to 0.080.01 to 0.08
Tin0 to 0.140.004 to 0.14
Titanium0 to 0.12 0.003 to 0.12
Vanadium0 to 0.22 0.008 to 0.22


AQuantitative range in accordance with Practice E1601.

Note 1--The concentration ranges of the elements listed have been established through cooperative testing of reference materials. These concentration ranges can be extended by the use of suitable reference materials.

1.2 This test method covers analysis of specimens having a diameter adequate to overlap the bore of the spark stand opening (to effect an argon seal). The specimen thickness should be sufficient to prevent overheating during excitation. A heat sink backing may be used. The maximum thickness is limited only by the height that the stand will permit.

1.3This 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.
