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. Only those inclusions present at the test surface can be detected. 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. 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 astm e45 their chemical identity.

While astm e45 methods are primarily intended for rating inclusions, constituents such as carbides, nitrides, carbonitrides, borides, and intermetallic phases may be rated using some of the microscopic methods.

This practice, however, does not address the astm e45 of such parameters. Only those inclusions present at the test surface can be detected.

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. 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. 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.

However, experience astm e45 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.

Although compositions are not identified, Microscopic methods place inclusions into one of several composition-related categories sulfides, oxides, and silicates—the last as a type of oxide. Active view current version of standard.

Metallographic techniques that allow simple differentiation between morphologically similar inclusions are briefly discussed. While aastm minimum level of deformation asfm not specified, the test methods are not suitable for use on cast structures or on lightly worked structures.

Materials with very low inclusion contents may be more accurately rated by e4 astm e45 analysis, which permits more precise microscopic ratings. In some astm e45, 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.

Non-metallic inclusions

Macroscopic methods include macroetch, fracture, step-down, and magnetic particle tests. Also, by agreement, qualitative practices may be used where only the highest severity ratings for each inclusion type and thickness are defined or the number of fields containing these highest severity ratings are tabulated. These inclusions are characterized by morphological type, that is, by size, shape, concentration, and distribution, but not specifically by composition.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices astm e45 determine the applicability of regulatory limitations prior to use.

While the methods are astm e45 intended for rating inclusions, constituents such as carbides, nitrides, carbonitrides, borides, and intermetallic phases may be rated using some of the microscopic methods. Values in parentheses are conversions and are approximate.

Macroscopic methods are not suitable for detecting inclusions smaller than about 0.

Values in parentheses are conversions and are approximate. Macroscopic methods include macroetch, fracture, step-down, and astm e45 particle tests. 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.
