ASTM B730
This specification covers nickel (UNS N02200), lowcarbon nickel (UNS N02201), and nickel copper alloy (UNS N04400) in the form of welded and annealed or welded and stress-relieved tube intended for general corrosive service and for mechanical applications. The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
