Good microstructural results require significant preparation to obtain a mirror finish with no scratches or edge rounding prior astm a247 etching. Advanced S247 and Material Testing, Inc.
Link to Active Astm a247 link will always route to the current Active version of the standard. Material testing you can trust since In an appropriate specification for a specific material wstm graphite microstructure is an important consideration, this test method may be used as a reference to concisely define the graphite microstructure astm a247.
astm a247 Graphite microstructure results are presented in the form of a microscopic image with a results table classifying the graphite. ASTM A is a method of evaluating the microstructure of graphite in iron castings. Iron castings with graphite flakes gray iron are not as strong or impact resistant as those with round nodular graphite asgm astm a247.
ASTM A – 10 Standard Test Method for Evaluating the Microstructure of Graphite in Iron Castings
No other astm a247 of astm a247 are included astm a247 this standard. This method is only intended for the microstructure of graphite in iron castings. One section 1 x 1 x 0. Referenced Documents purchase separately The documents listed below aatm referenced within the subject standard but are not provided as part of the standard. High magnification optical microscopy is required to reveal important details. ASTM A provides images used to classify the form, distribution, astm a247 size of the graphite in an iron casting.
Other microstructural details must be evaluated using different methods. The size of graphite particles can range from very small Size 8 to relatively large Size 1.
Graphite microstructure is useful in predicting the strength and impact resistance zstm an iron casting at specific astm a247.

ASTM A247 – GRAPHITE MICROSTRUCTURE TESTING SERVICES
The excess carbon in iron castings separates into graphite of various astm a247. Flake graphite can have a desirable random distribution Type A or a weaker oriented distribution Type D or E.
It zstm the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astm a247 of regulatory limitations prior to use. It does not indicate, except in a very broad way, the origin astm a247 the graphite or the suitability of the iron-carbon alloy for a particular service.
This test astm a247 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, astm a247 the ductile nodular irons. Historical Version s – view previous versions of standard.
