scope:

1.1 This practice covers procedures and definitions for estimating ferrite content in stainless steel alloys containing both austenite and ferrite phases in amounts controlled to be within specified limits. Methods are described for estimating ferrite content by chemical, magnetic, and metallographic means.

Note 1: This practice can be used for cast austenitic and duplex stainless steel alloys (for example, CF-3, CF-3A, CF-8, CF-8A, CF-3M, CF-3MA, CF-8M, CF-8C, CG-8M, CH-10, CD4MCuN (1B), CD3MCuN (1C), CE8MN (2A), CD6MN (3A), CD3MN (4A), CE3MN (5A), CD3MWCuN (6A), and CD3MWN (7A)).

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. 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 practice.

1.2.1 Within the text, the SI units are shown in brackets.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 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.
