Iron castings with graphite flakes gray iron astm a247 not as strong or impact resistant as those with round nodular graphite ductile iron.
It is the responsibility of the user of this standard to establish astm a247 safety and health practices and determine the applicability of regulatory limitations prior to use.
It does not indicate, except in a astm a247 broad way, the origin of the graphite or the suitability of the iron-carbon alloy for a particular astm a247. Other microstructural details must be evaluated using different methods.
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.

Historical Version s – view previous versions zstm standard. Graphite microstructure results are presented in the form of a microscopic image astm a247 a results table classifying the graphite.
High magnification optical microscopy is required to reveal important details. Flake graphite astm a247 have a desirable random distribution Type A or astm a247 weaker oriented distribution Type D or E. ASTM A is a method of evaluating the microstructure of graphite in iron castings. Advanced Plastic and Material Testing, Inc.
Good astm a247 results require significant preparation to obtain a mirror finish with no astm a247 or edge rounding prior to etching. This method is only intended for the microstructure of graphite in iron aatm.
astm a247 No other units of measurement are included in this standard. Link to Active This link will always route to the current Active version of the standard. ASTM Astm a247 provides images used to classify the form, distribution, and size of the graphite in an iron casting.
Graphite microstructure is useful in predicting the strength and impact resistance of an iron casting at specific locations. The astm a247 carbon in iron castings separates into graphite of various forms.
