ABSTRACT
This specification2 covers rod of low-carbon nickel-chromium- molybdenum alloys (UNS N10276, N06022, N06035, N06455, N06058, and N06059), low-carbon nickel-molybdenum- chromium-tantalum (UNS N06210), low-carbon nickel-chromium-molybdenum-copper alloy (UNS N06200), and low-carbon nickel-chromium-molybdenum-tungsten (UNS N06686), for use in general corrosive service. Product and chemical analyses shall be performed on the materials and shall conform to the required chemical composition in molybdenum, chromium, iron, tungsten, cobalt, carbon, silicon, manganese, vanadium, phosphorus, sulfur, titanium, nickel, aluminum, copper, and tantalum. Tension test shall be performed and shall comply to required mechanical properties for hot or cold finished, solution annealed rods such as tensile strength, yield strength, and elongation.
SCOPE
1.1 This specification2 covers rod and bar of low-carbon nickel-chromium-molybdenum alloys (UNS N10276, N06022, N06035, N06044, N06455, N06058, and N06059), low-carbon nickel-molybdenum-chromium (USN N10362), low-carbon nickel-molybdenum-chromium-tantalum (UNS N06210), low-carbon nickel-chromium-molybdenum-copper alloy (UNS N06200), and low-carbon nickel-chromium-molybdenum-tungsten (UNS N06686) as shown in Table 1, for use in general corrosive service.      
1.2 The following products are covered under this specification:  
1.2.1 Rods and Bars 5/16 in. to 3/4 in. (7.94 mm to 19.05 mm), exclusive, in dimension3, solution annealed and pickled, or mechanically descaled.  
1.2.2 Rods and Bars 3/4 in. to 31/2 in. (19.05 mm to 88.9 mm), inclusive, in dimension3, solution annealed, ground or turned.  
1.2.3 Rods and Bars 1/4 in. to 3 1/2 in. (6.35 mm to 88.9 mm), inclusive, in dimension3, solution annealed, cold worked, ground or turned (N06022, N06059, N06686, and N10276, see Table 2 and Table 3).  
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, health, and environmental 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.

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.
