Standard Specification for UNS N08925, UNS N08031, UNS N08932, UNS N08926, <brk/>UNS N08354, UNS N08830, and UNS R20033 Plate, Sheet, and Strip

ABSTRACT
This specification covers alloys UNS N08925, UNS N08031, UNS N08932, UNS N08926, UNS N08354, and UNS R20033 plate, sheet, and strip in the annealed temper. The alloys shall conform to the required chemical composition such as carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, nitrogen, and iron. The alloys shall also conform to the required mechanical properties such as tensile strength, yield strength, elongation, and Rockwell hardness.
SCOPE
1.1 This specification covers alloys UNS N08925, UNS N08031, UNS N08932, UNS N08926, UNS N08354, UNS N08830, and UNS R20033 plate, sheet, and strip in the annealed temper.  
1.2 ASTM International has adopted definitions whereby some grades, such as UNS N08904, previously in this specification were recognized as stainless steels, because those grades have iron as the largest element by mass percent. Such grades are under the oversight of ASTM Committee A01 and its subcommittees. The products of N08904 previously covered in this specification are now covered by Specifications A240/A240M and A480/A480M.  
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 Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
