ASTM B435-22

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.

This standard is issued under the fixed designation B435; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This specification covers alloys UNS N06002, UNS N06230, UNS N12160, and UNS R30556in the form of rolled plate,
sheet, and strip for that are typically used for (though not limited) heat-resisting and general corrosive service.
1.2 The following products are covered under this specification:Alloys that can currently be certified to this specification are UNS
N06002, UNS N06230, UNS N12160, and UNS R30556.
1.2.1 Sheet and Strip—Hot- or cold-rolled, annealed, and descaled unless solution annealing is performed in an atmosphere
yielding a bright finish.
1.2.2 Plate—Hot-rolled, solution-annealed, and descaled.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.4 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet
(SDS) for this product/material as provided by the manufacturer, to establish appropriate safety safety, health, and healthenvi-
ronmental practices, and determine the applicability of regulatory limitations prior to use.
1.5 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.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 plate, n—material ⁄16 in. (4.76 mm) and over in thickness.
3.1.2 sheet and strip, n—material under ⁄16 in. (4.76 mm) in thickness.
3.1 Common B02.07 terminology is found in Specification B899.
3.2 The definitions for plate, sheet, and strip used in Specification B906 apply to the products of this specification with the
following adjustments:
3.2.1 Strip can be either a cold rolled or hot rolled material.
3.2.2 The finishes allowed for products certified to this specification are stipulated in Section 6.
4. General Requirements
4.1 Material furnished under this specification shall conform to the applicable requirements of Specification B906 unless otherwise
provided herein.
