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 – 17 Standard Test Method for Evaluating the Microstructure 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.

Iron castings with graphite flakes gray iron are not as strong or impact resistant as those with round nodular graphite ductile iron.
