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.

This method is only intended for the microstructure of graphite in iron castings.

ASTM A247 – GRAPHITE MICROSTRUCTURE TESTING SERVICES

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. Graphite microstructure is useful in predicting the strength and impact resistance awtm an iron casting at specific locations.

ASTM A provides images used to classify the form, distribution, and size of the graphite in an iron casting. Need more than one copy?

Good microstructural results require significant preparation to obtain a mirror finish with no scratches or edge rounding prior to etching. Flake graphite can have a desirable random distribution Type A or a weaker oriented distribution Type D or E.

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

This test method is ast, 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. This standard is not included in any packages. Other microstructural details must be evaluated using different methods. Work Item s – proposed revisions of this standard. The excess carbon in iron castings separates into graphite of various forms. Iron castings with graphite flakes gray iron are not as strong or impact resistant as those with round nodular graphite ductile iron.
