ASTM A247 PDF

ASTM A Standard Test Method for Evaluating the Microstructure of Graphite in Iron Castings. ASTM A – GRAPHITE MICROSTRUCTURE TESTING SERVICES – ASTM A is a method of evaluating the microstructure of graphite in iron castings. The most common gray iron specification will contain Type VII flakes, type A, size , as evaluated in ASTM A Dura-Bar G2 gray iron will contain this type of.

ASTM A – Standard Test Method for Evaluating the Microstructure of Graphite in Iron Castings

Graphite microstructure results are presented in the form of a microscopic image with a results table classifying the graphite. 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. If the document is revised or amended, you will be notified by email. The excess carbon in iron castings separates into graphite of various forms.

It does not indicate, except in a very broad way, the origin of the graphite or the suitability of the iron-carbon alloy for a particular service. Subscription pricing is determined by: Your Alert Profile lists the documents that will be monitored.

This method is only intended for the microstructure of graphite in iron castings. Graphite microstructure is useful in predicting the strength and impact resistance of an iron casting at specific locations. No other astk of measurement are included in this standard. Your Alert Profile sstm the documents that will be monitored. Good microstructural results require significant astj to obtain a mirror finish with no scratches or edge rounding prior to etching. 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 define concisely the graphite microstructure required.
