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

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 concisely define the graphite microstructure required. Already Subscribed to this document. ASTM A provides images used to classify the form, distribution, and size of the graphite in an iron casting. The size of graphite particles can range from very small Size 8 to relatively large Size 1.

ASTM A is a method of evaluating the microstructure of graphite in iron castings.

Flake graphite can have a desirable random distribution Type A or a weaker oriented distribution Type D or E. Iron castings with graphite flakes gray iron are not as strong or impact resistant as those with round nodular graphite ductile iron.
