ASTM B1020/B1020M-22

Standard Specification for Seamless Nickel Alloy Mechanical Tubing and Hollow Bar

SCOPE
1.1 This specification covers seamless nickel alloy tubing for use in mechanical applications or as hollow bar for use in the production of hollow components such as, but not limited to, nozzles, reducers, and couplings by machining where corrosion-resistant or high-temperature strength is needed. The grades covered are listed in Table 1.  
1.2 This specification covers seamless cold-finished mechanical tubing and hollow bar, and seamless hot-finished mechanical tubing and hollow bar in sizes up to 123/4 in. [325 mm] in outside nominal diameter (for round tubing) with wall thicknesses or inside diameters as required.  
1.3 Optional supplementary requirements are provided and when desired, shall be stated in the order.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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.
