Standard Specification for Steel Castings, Austenitic Manganese

Fecha:
2019-05-03 /Active
Abstract:

This specification covers Hadfield austenitic manganese steel castings and alloy modifications. The castings shall be suitably heat treated to achieve toughness and ductility. This heat treatment shall consist of uniformly heating the castings to a temperature applicable for grade of steel produced. The steel shall conform to the requirements as to chemical composition prescribed. Weld repairs shall be inspected to the same quality standards as are used to inspect the castings.

Scope:

1.1 This specification covers Hadfield austenitic manganese steel castings and alloy modifications.

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
