Abstract
This specification covers plate, sheet, and strip of low-carbon nickel-chromium-molybdenum alloys (UNS N10276, N06022, N06455, N06035, UNS N06058, UNS N06059), low carbon nickel-chromium-molybdenum-copper alloy (UNS N06200), low-carbon nickel-chromium-molybdenum-tantalum alloy (UNS N06210), and low-carbon nickel-chromium-molybdenum-tungsten alloy (UNS N06686) for use in general corrosive service. The materials shall conform to the required chemical composition for molybdenum, chromium, iorn, tungsten, cobalt, arbon, silicon, manganese, vanadium, phosphorus, sulfur, titanium, nickel, aluminum, copper, and tantalum. The alloys shall connform to the required tensile properties such as tensile strength, yield strength, elongation, and Rockwell hardness. Sheet and strip shall conform to the required grain sizes. Dimensions such as plate, sheet and strip thickness, width, length, straightness, squareness, flatness and edges shall be determined.

(A) D refers to the diameter of the tension specimen.
(B) Hardness values are shown for information purposes only and are not to be used as a basis of acceptance or rejection. For approximate hardness conversions, see Hardness Conversion Tables E140.
1.2 The following products are covered under this specification:
1.2.1 Sheet and Strip—Hot or cold rolled, solution annealed, and descaled unless solution anneal is performed in an atmosphere yielding a bright finish.
1.2.2 Plate—Hot or cold 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 and health 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.
