No other units of measurement are included in this standard. It does not indicate, except in a very broad way, the origin of the graphite or the suitability of the iron-carbon astm a247 for a particular service.

ASTM A247 – GRAPHITE MICROSTRUCTURE TESTING SERVICES

Graphite microstructure results are presented in the form of a microscopic image with a results table astm a247 the graphite. Material testing you can trust since The size of graphite particles can range from very small Size 8 to relatively large Size 1. Historical Version s – view previous versions of standard.

Link to Active This link will always route to the current Active version of the standard. Flake graphite can have a astm a247 random distribution Type A or a weaker oriented astm a247 Type D or E. In an appropriate specification for a specific material where graphite microstructure is an important consideration, this test method may be used as a reference to concisely define the graphite microstructure required.

This test method is intended to be applicable for all iron-carbon alloys containing graphite particles, and may be applied to gray irons, malleable irons, compacted graphite irons, and the ductile nodular irons. Our laboratory also provides laboratory services for plastic testingmetal testingrubber testingastm a247 testingpaint testingplating testingadhesive testingcircuit astm a247 testingand other testing.

Graphite microstructure is useful in predicting the strength and impact resistance of an iron astm a247 at specific locations. The excess carbon in iron castings separates into graphite of various forms.

This method is only astm a247 for the astm a247 of graphite in iron castings. 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.

Referenced Documents astm a247 separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Iron castings with graphite flakes gray iron are not as strong astm a247 impact resistant as those with round nodular graphite ductile iron.

Good microstructural results require significant preparation to obtain a mirror finish with no scratches or edge rounding prior to etching.

ASTM A provides images astm a247 to classify the form, distribution, and size of the graphite in an iron casting. ASTM A is a method of evaluating the microstructure of graphite in iron castings.
