(Specification)Standard Specification for Abrasion-Resistant Cast Irons
Standard Specification for Abrasion-Resistant Cast Irons
ABSTRACT
This specification deals with abrasion-resistant cast irons used for mining, milling, earth-handling, and manufacturing industries. 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. The following conditions for casting will be supplied: as-cast, as-cast and stress relieved, hardened, hardened and stress relieved, or softened for machining. Heat treatment shall be done. The chemical composition of a class and type (that is, Class I, Type A) shall conform to the range of values specified for carbon, manganese, silicon, nickel, chromium, molybdenum, copper, phosphorus, and sulfur. Hardness test shall also be made.
SCOPE
1.1 This specification covers a group of white cast irons that have been alloyed to secure high resistance to abrasive wear in the applications of the mining, milling, earth-handling, and manufacturing industries.
1.2 Simple and low-alloy white cast irons that consist essentially of iron carbides and pearlite are specifically excluded from this specification.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

5. Heat Treatment
5.1 The casting will be supplied in one of the following conditions:
5.1.1 As-cast,
5.1.2 As-cast and stress relieved,
5.1.3 Hardened,
5.1.4 Hardened and stress relieved, or
5.1.5 Softened for machining.
5.2 Unless otherwise specified by the purchaser, the manufacturer shall supply the castings in the heat treatment he deems best
for the application.
5.3 If the heat treatment specified for delivered condition is not that of final use, it shall be the responsibility of the purchaser
to provide the additional heat treatment.
5.4 Class II and Class III alloys are frequently ordered in the annealed condition with a maximum hardness of 400 HB. After
machining operations are performed the castings may then be hardened. If both annealing and machining are to be performed by
the manufacturer, as specified in the inquiry, contract, or order, the purchaser may then specify delivery in the hardened condition.
If the purchaser specifies delivery in the annealed condition, subsequent hardening (and stress-relief, if it is desired) is the
responsibility of the purchaser.
