Other microstructural details must be evaluated using different methods. High magnification optical microscopy is required to reveal important details.

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 astm a247, and xstm ductile astm a247 irons. Historical Version s – view previous versions of standard.

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

astm a247 Graphite microstructure is useful in predicting the strength and impact resistance of s247 iron casting at specific locations. Flake graphite can have a desirable random distribution Type A or a weaker oriented distribution Type D or E. Link to Active Astm a247 link will always route to the current Active version of the standard.

Good microstructural results require significant preparation to obtain a mirror finish astm a247 q247 scratches or edge rounding prior to etching. Graphite microstructure results are presented in the form of a microscopic image with a results table classifying the graphite.

Material testing you can trust since The size of graphite particles can range from very small Astm a247 8 to relatively large Size 1. It does not astm a247, except in a very broad way, the origin of the graphite or the suitability of the iron-carbon alloy for z247 particular service. No other units of measurement are included in this standard.

It is the responsibility astm a247 the user of astm a247 standard to establish appropriate safety and health aatm and determine the applicability of regulatory limitations prior to use.

The excess carbon in iron castings separates into graphite of various forms. ASTM A is a method of evaluating the microstructure of graphite in iron castings. One section 1 x 1 x 0.

Iron castings with graphite flakes astm a247 iron are not as strong or impact resistant as those with round nodular graphite ductile iron. ASTM A provides images used to classify the form, distribution, and size of the graphite in an iron casting. This method is only intended for the microstructure of graphite in iron castings.

In an astm a247 specification for a specific material where graphite microstructure is an important consideration, this test method may be used astm a247 a reference to concisely define the graphite microstructure required.
