However, experience and knowledge of the casting process and production materials, such as deoxidation, desulfurization, and inclusion shape control additives as well as refractory and furnace liner compositions must be employed with the microanalytical results to determine if an inclusion is indigenous or exogenous.

Microanalytical techniques such as energy dispersive X-ray spectroscopy EDS may be used to aid in determining the nature of the mwthod.

MSQ Inclusion Rating

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Inclusions are measured and rated quickly and accurately. While a minimum level of deformation is not specified, the test methods are not suitable for use on cast structures or on lightly worked structures.

When such steels are evaluated, the test report should describe the nature of the inclusions rated according to each inclusion category A, B, C, D. These test methods deal only with recommended test methods and should not be construed as defining or establishing limits of methdo for any grade of steel. All measurements and statistical results are sent automatically to an Excel report.


We employ an automated image analysis system by Clemex Technologies, which provides standardized programming that conforms to many of the following specifications. Qualification criteria for assessing the data developed by these methods can be found in ASTM product standards or may be described by purchaser-producer agreements.

Both Method A and Method D reports can be produced. Click on the View Results button for an example.

In case of a dispute whether an inclusion is indigenous or exogenous, microanalytical techniques such as energy dispersive X-ray spectroscopy EDS may be used to aid in determining the nature of the inclusion. Measurement with the click of one button. Values in parentheses are conversions and are approximate. Convenient controls for correcting methoe illumination. This practice, however, does not address the measurement of such parameters.

There are a number of microscopic test methods that have been e54 to determine the non-metallic inclusion content of wrought steel. The report may be changed to any format, saved and printed. Only those inclusions present at the test surface can be detected. Set reject levels for automatic logging of any rejectable inclusions.

Inclusion Rating Testing

The microscopic methods are not intended for assessing the content of exogenous inclusions those from asstm slag or refractories. Number of fields rated and total area rated are constantly displayed. Microscopic methods include five generally accepted systems of examination. Although compositions are not identified, Microscopic methods place inclusions into one of several composition-related categories sulfides, oxides, and metod last as a type of oxide.

In some cases, alloys other than steels may be rated using one or more of these methods; the methods will be described in terms of their use on steels. It is the responsibility of the aatm of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.


The degree of sampling must be adequate for the lot size and its specific characteristics. In these microscopic methods, inclusions are assigned to a category based on similarities in morphology, and not necessarily on their chemical identity. Macroscopic methods include macroetch, fracture, step-down, and magnetic particle tests.

ASTM E45 – 18a Standard Test Methods for Determining the Inclusion Content of Steel

Special Aircraft Quality Steel Cleanliness: These inclusions are characterized by morphological type, that is, by size, shape, concentration, and distribution, but not specifically by composition. Rate live samples using camera on and off switch, or stored file images may be measured. Easy to set controls for detecting both sulfide and oxide type inclusions.

For each method, inclusions are assigned to a category based on similarities in morphology, and not necessarily on their chemical identity. By agreements between producer and purchaser, these test methods may be modified to count only certain inclusion types and thicknesses, or only those inclusions above a certain severity level, or both.

Results are immediately displayed. Link to Active This link will always route to the current Active version of the standard. Materials with very low inclusion contents may be more accurately rated by automatic image analysis, which permits more precise microscopic ratings. Also, by agreement, qualitative practices may be used where only the adtm severity ratings for each inclusion type and thickness are defined or the number of fields containing these highest severity ratings are tabulated.
