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 A247 – GRAPHITE MICROSTRUCTURE TESTING SERVICES

Please first log in with a verified email before subscribing to alerts. Iron castings with graphite flakes gray iron are not as strong or impact resistant as those with round nodular graphite ductile iron. 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 define concisely the graphite microstructure required.

This test method is intended to be applicable for all iron-carbon alloys containing graphite particles, and may be applied to gray sstm, malleable irons, compacted graphite irons, and the ductile nodular irons. No other units of measurement are included in this standard.

This standard is not included in any packages.

High magnification optical microscopy is required to reveal important details. Good microstructural results require significant preparation to obtain a mirror finish with no scratches or edge rounding prior asfm etching. Standards Subsctiption may be the perfect solution.

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

Please first verify your email before subscribing to alerts. 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 results are presented in the form of a microscopic image with a results table classifying the graphite. Flake graphite can have a desirable random distribution Type A or a weaker oriented distribution Type D or E. Standards Asmt may be the perfect solution.
