Metallurgy, Plymouth Tube RE: A53 is the part under consideration. These alloys may be made by melting process and shall have microstructures that consist of carbides, martensite, bainite, austenite, and in exceptional cases, minor amounts of graphite or pearlite.

Heat treatment shall be done.

This specification deals with abrasion-resistant cast irons used for mining, milling, earth-handling, and manufacturing industries. Hi arunmrao, attached is an image of the part in question, already cast and HRC ish, and needing machining of several features. Combining values from the two systems may result in non-conformance with the standard.

The following conditions for casting will be supplied: You need to check on the current structure, and perhaps do some trials. Please contact us at webmaster matweb.

The castings already are distorted enough to require dimensional compromises. Property Data This page displays only the text astk a material data sheet.
